I'm not sure that I understand what you are asking. The log-likelihood
function of the data is a well defined concept. Since in GARCH the
residuals are conditionally normal/student-t/whatever distributed, the
likelihood function will always be expressed in terms of the residuals and
their conditional moments.

Cheers

Sorry, I've just got back from a few weeks in Canada and haven't had time
to look at your code properly.

I can, however, pass on two tips which I think were incorporated in my
sample code which Estima published. One thing to watch when you code the
Student-t is that your 'H' is still the conditional variance. If you just
take the usual way of writing the Student-t, you'll find that the
conditional variance is then something like H*df/(df-2.0). (So switching
likelihood functions will produce variances and standardised residuals of
the wrong scale.) I think you'll find that Tim Bollerslev's
parameterisation (see some of his papers) of the Student-t avoids this
problem - ie the conditional variance is still 'H'. (You may also want to
think about whether you estimate 'df' or '1/df' as the degrees of freedom
parameter - esp if you want to conduct statistical tests on its value.)

Hello,

What is the best way to do the following in RATS.

Thanks.

Regards, Kenneth.

--------------------------------------------------------------

The regression model is:

Y = a + bX + cW + dZ + u

where the coefficients a, b, c, and d are scalars.

I would like to perform (forward) recursive OLS estimates of this model,
ie. the samples

1962:1-1970:4
1962:1-1971:4
1962:1-1972:4
....
1962:1-1990:4 

and, at each stage, compute the F-statistic for H0: c = d = 0.

Also, I would like to perform (backward) recursive estimates, ie. the
samples are:

1965:1-1990:4
1966:1-1990:4
1967:1-1990:4
....
1985:1-1990:4

and, again, calculate the F-statistic for H0: c = d = 0 at each stage.

The aim is to get a vector of F-statistics (and, if possible, the associate
probability values) for each sub-sample, eg.

Sample			F(c,d)
1962:1-1970:4		3.458
1962:1-1971:4		6.512*
....
1962:1-1990:4		1.265

I think that Steve has some of his code on his web-site at Duke. It may be
in GAUSS, but could probably be recoded into RATS.

Hi,

A very simple Eviews .prg file for the HEGY test using quarterly data,
which can be easily converted in RATS format is:

------------------------------------------------------------------------
genr t=@trend(1959:2)
genr y=gdp
genr hd=D(y,0,4)
genr h1=y(-1)+y(-2)+y(-3)+y(-4)
genr h2=-y(-1)+y(-2)-y(-3)+y(-4)
genr h3=-y(-2)+y(-4)
genr h4=-y(-1)+y(-3)

ls hd  t  h1 h2 h3 h4 @seas(1) @seas(2) @seas(3) @seas(4) hd(-1 to -7)

I have 10 time series and need to do a cross-sectional ranking at each time 
period.  Using recursive %MAX or %MIN will be very inefficient.  Anyone aware 
of a simple command in RATS for that?  Something like ORDER for time series 
reordering?

Thanks.

Having done something very similar recently in Mathematica, what about 
MAKEing the T x k matrix from these timeseries, transpose it, "unmake" 
it and run ORDER inside a loop? That will quickly generate the 
"scores", which can then readily be moved back to T x k format.

Fellow RATS users:

Is there a readily available procedure or example code for performing the
Chow and Lin (ReStat 1971) procedure for interpolating, for example, a
quarterly frequency series to monthly using a related monthly series?

Any assistance would be greatly appreciated.

I have a database which has the breakdown of daily trading of an
interest rate variable.  Unfortunately, the data is organized so that for
each day I have the number of occurrences of a particular yield, when
what I really want is a timeseries where for each day, every occupance
of an individual rate is a single observation.  Therefore, I need to expand
this database.

At present the database looks like the following matrix:

Rate/Date    6/11/97   6/12/97
5%                500           300
5.25%           200        1,000
5.50%           800           400

where, for example, the number 200 represents the number of times the
market traded at 5.25%, and what I want is a series for 6/11/96 in which
I have 200 observations at 5.25%.

Thus, part of the problem is the correct way of reading this data into
Rats so that I can convert it into the correct format.

Does anyone have any suggestions/sample programs as to reading the
data in and then expanding it into a series of observations.

Gerald:

I didn't notice your post until just now. I might be able to offer 
some suggestions, but I just wanted to clarify the task at hand.

If I understand you correctly, you would want, for example, a series
for June 11, which would have 500 observations containing the value
"5", 200 observations containing the value "5.25" and 800
observations containing the value "5.5". Let me know if this is 
correct.

Sincerely,
Tom Maycock

Is anyone still running System 6.x? If so, let me know soon. 

The upcoming MacRATS release will almost definitely require System
7.x, but if there are lots folks of still running System 6, we MAY be 
able to continue supporting it.

Tom, this is a silly question, as any (030-040) machine out there is 
capable of running system 7.1, and anyone who has not managed to 
upgrade to that level to take advantages of the many 
improvements in the system software probably couldn't figure out how to 
install MacRATS. For instance, we have email software campuswide that 
requires Sys 7.5 at this point, and scientific word processing 
software that won't even run on a 68K Mac. So yes, requiring Sys 7.x is 
certainly not going to cut off a meaningful fraction of the serious 
market, and you shouldn't worry about Sys 6. Just make sure it works 
fine on Sys 7.6.1 and Sys 8!

Tom,

I am at 7.6 and hope you will provide me with some sort of a new version
sooner than later.  My opinion is that most Mac users are well beyond 6.0
for a variety of reasons; technical and otherwise.  As the ad says, just do
it.

Tom, I think so few Mac users still use System 6 that it wouldn't
be worth the time or effort to make sure the next MacRATS release
will be compatible with it.  I might be wrong, of course.  I do
not know anyone, however, who uses System 7.1 anymore, let alone
System 6.

By the way, will there be a PowerPC native version?


Thanks,

I agree with this - a lot of the software you see around these days
requires System 7.1 or greater. I would seriously doubt if any of your
customers would be using System 6 on machines on which they use RATS. I
would expect that most would use System 7.5.5 or 7.6.1 - although if
there's no reason to require this you may be better assuming System 7.1 or
better.

Tom,

Currently 7.5.5 and we are looking at a beta of 8.

Are you looking at Blue and Yellow box compatability?

Does this mean there is light at the end of the tunnel (or is it just an
onrushing train)?

Thanks,

Mark :-{)

There had better be a PPC native version! For any program 
heavily dependent on numerical computation, it is essential to make use 
of the PPC built in FPU, and without a PPC native version, you can't do 
that. Emulating the FPU is not an option for a credible product--not 
when most apps run 10x faster in native PPC mode (that was the 
published benchmark for Mathematica 2.2; your mileage may vary).

I am attempting to use RATS to form a Wald chi-squared test on non-linear
restrictions on a VAR companion matrix.  This matrix involves the gradient
of the companion matrix with respect to the original VAR parameters.  An
example of what I have in mind can be found in a couple of references:
Campbell, Econometrica, 1987, pp. 1257-8, 1264; Ghosh, Economic Journal,
1995, p. 122).  It would be particularly useful to know how RATS can
formulate (what code to use) the test statistics shown on p. 1264 and p. 122
of these two articles respectively.  Estima seemed unable to understand
these tests or offer any useful suggestions.  If in your experience, you
have needed to make such tests and used some other program because RATS
lacked a suitable routine, please provide whatever details you can about
this.  I would be most grateful for any help on this.

OK, let me try this again:

I'm assuming that everyone using MacRATS is indeed running System
7.x, and has been for a long time. 

I simply want to know if anyone is in fact still stuck with System 6 
for some reason. 

No, it probably won't matter, because RATS will almost certainly
require System 7 anyway. Nevertheless, I'd like to know, just for my 
own edification.

So, e-mail me directly if you are in fact still using System 6. 

Please, please, please, do not e-mail me simply to say that you are,
in fact, using System 7, as I'm assuming that already. 

Other suggestions/comments are, of course, always welcome and 
appreciated!

Thanks again, and sorry for the bandwidth.

Tom Maycock

Absolutely not true, and very rude of you say this. If you like, I'd
be more than happy to explain to everyone on the list why I declined

Dear Mac people:

Ooops, due to a mail glitch, my follow up to Kit Baum's first
message, which I wrote yesterday, didn't get sent out until this
morning--after a bunch of other folks posted replies.

So, let me try this a third time, with apologies to non-Mac users for 
wasted bandwidth:

First, regarding my post about System 6, let's just pretend I never
brought it up, OK? 

Now, I think my real mistake was asking the System 6 question
without first satistfying everyone's appetite for real news on the
Mac release. Let me try to fix that now:

The Mac version is indeed our main focus right now. Mr. Doan feels we
should have a test release (late alpha/early beta stage) ready in two
or three weeks. I'll be getting in touch with people about being beta
testers.

At the moment, we have tentative plans to release two versions of
MacRATS 4.3:

There will obviously be a native PowerPC version. We'll probably
release that version as a fat binary, as long as there's no
performance trade off in doing so (and there shouldn't be). This way,
users would be able to run it on non-PowerPC machines as well (which
should be handy for people with a PowerPC desktop and an 040 laptop,
etc.). 

We'll probably also release a 680x0-only version, if for no other
reason than to provide a free update path for users with the standard 
version of MacRATS.

Again, this is tentative and may change.

Regarding System 8 compatibility, that shouldn't be a problem. We
probably won't take the time to test against Sys. 8 until after the
first beta release of RATS is out. The official release version of 
System 8 should be out around that time (IF Apple stays on schedule), 
so we should be able to fully test subsequent beta versions and the 
release version of MacRATS on System 8.

Regarding Rhapsody, Yellow box, Blue box, pink box, red box, etc.,
we've got enough work to do just to get a System 7/8 version out, so
I think we'll worry about crossing the Rhapsody bridge when it
actually gets closer to being built. 

Thanks,
Tom Maycock

	Thanks for the update on the status of MacRATS -- the news sounds 
fairly encouraging.  One aspect that I hope is incorporated into the 
latest release (or an update soon thereafter) is support for RGF 
formatted graphics files.  For myself, portability between the Unix and 
Mac versions is important.  (And thank goodness one can finally view RGF 
files in X-windows, without having to resort to GRAFEDIT on a PC!  Who 
has one of *those* lying around?!  ;) )

	Some specific thoughts on your message:

1.  Thank you for releasing a fat binary version;  I am exactly in the 
situation you mention (PPC desktop, '040 laptop).  I'm not aware of there 
being any risk of a performance hit through a fat binary -- indeed, since 
it allows each processor to execute native code, this can only be an 
improvement over a non-native version.  The only cost is slightly larger 
files, but there are utilities which can slim down the file size by 
stripping out non-native code. 

2.  As long as your programmers avoid low-level system calls, MacRATS
should run just fine in the Blue Box, which, according to my information, 
simply emulates MacOS 7.x/8.x (similar to MAE on Unix).  Of course, it 
never hurts to test....  IMHO, MacOS 8 compatibility is more important in 
the near term, though not inconsistent with compatability for the Blue Box.

3.  One question:  what is the likely cost structure for the upgrade? 


Thanks again for the update.  Looking forward to the product itself! 

P.S.  Still looking for beta testers??

This is my understanding as well, so at the moment, I don't see any
reason why we won't do it as a fat binary. If we don't go the fat
binary route for some reasons, we can certainly ship both the 680x0
and PowerPC executables to customers with PowerPC licenses.

Yep, that's how I understand it as well. So, as you suggest, I think 
will aim for System 8 compatibility now, and tweak later as needed 
for Rhapsody, etc.

No final decisions have been made, but here's what we are thinking as 
of now:

Users with MacRATS '020 4.x will probably get free updates to the
PowerPC version of MacRATS 4.3. Frankly, we'd like to charge
something for the upgrade to a PowerPC-native version, but we don't
think that would be fair, given the fact that Mac customers have been
waiting so long for updates.

Users with standard MacRATS will get free updates to the 680x0 
version of MacRATS 4.3. They'll be able to upgrade to the PowerPC 
version for somewhere around $100 (the same as we currently charge to 
go from MacRATS to MacRATS '020).

Re. beta testers, I'll be sure to check with the mailing list when 
we're ready to go.

Thanks,
Tom Maycock

Yes, it certainly is important. More generally, I think binary
compatibility of RGF files across all platforms is important. (We already
have it for RATSDATA files with v4.)

Well, I'm not quite sure what you are looking for in terms of
"improved", but the update will include the 4.2 and 4.3 manual
supplements that describe new/modified features. It will probably 
also include a Mac-specific "Getting Started" manual, similar to what 
we do for the PC/Windows version--this is basically a more in-depth 
version of the old "Installation and Use Guide".

Regarding support for RGF files with the Mac version, we hadn't
really talked about that. Because the internal handling of graphics
was completely overhauled with 4.2 anyway, it might not be too
difficult. On the other hand, it might be very difficult, and I'd
hate to delay the thing even longer. I'll chat with the boss and let
you know if I have any news on that front.

 Hi Tom,

As Mary Walsh, our famous comedian for the Atlantic Region of Canada would
say, now mind you she is not all that large geographically, but never the
less otherwise is rather robust, oops excuse the metifore, would say "my
gills are filled with expectations and a wondering if it is really true
that sweet and loveable lad in the states will bless us with his wisdom and
grace.  God bless you my boy and a cod cheek sandwich is on the way."

From Screeching John somewhere in the Maritimes lost in his old  MAC RATS.

Just wanted to let you know that the upcoming Mac version should
indeed support RGF format files. As part of the 4.2 redesign of the
graphics engine, everything is handled in memory in "RGF" format on
all platforms. So, it will be a simple matter to allow MacRATS to
read and write RGF files written by any 4.2x or later version of
RATS on any platform.

And, as with the DOS and Windows versions, you should be able to save 
directly to PostScript format. I assume we will continue to allow 
saving to PICT format as well.

More later,
Tom Maycock

Hi,

I'm try to simulate a VAR using the IMPULSE command with the paths option
to input a series of shocks. Although this series has a couple of hundred
observations and my VAR has been estimated over the same span I cannot get
RATS to give me any more than 110 observations in my responses. Is this a
dimension problem with RATS? Has anyone come across something similar? Is
there a solution?

Many Thanks
