Description

Commands that provide a convenient way to describe the variables
generated with sqegen. The commands are useful because SQ-data
is in long form, while the variables generated with sqegen
refer to the sequences as entire entity. To further describe the new
variables one might want to reshape the data to wide. The
sqstat-commands allow to summarize, tabulate, and list the
variables generated with the sqegen function as if the data were
in wide format. Thereby the names of the variables generated with
sqegen are automatically processed.

The following sqstat programs are available:

sqstatlist [varlist] [ , replace ranks(numlist) ]:
Lists all variables generated with
sqegen. With varlist only the specified variables are
listed. replace is used to keep the listed dataset in
memory. This is useful to produce some non-standard description (like
graphs, for example) of the e-generated variables. ranks() is
used to restrict the output to the most frequent sequences. Inside the
parentheses a numlist might be specified, which refer to the
position of the sequences in the sorted frequency table.

sqstatsum [varlist]: If given without the optional
varlist the command summarizes all variables generated with the
sqegen bundle. With varlist only the specified variables are
summarized.

sqstattab1 [varlist]: If given without the optional
varlist the command produces one way frequency tables of all variables
generated with the sqegen bundle. With varlist only the
specified variables are used.

sqstattabsum varname1 [varname2 ]: Summarizes
all e-generated variables for categories of the specified
variables. Option format(%fmt) allows to set the display
format of all cells in the output. The default is %9.0g.

sqstattab2 varname1 [varname2]]: If given
without the optional varname2 the command displays a two-way table of
varname1 against all variables generated with the sqegen
bundle. If specified with varname2 a two-way table of the two
specified variables is displayed.

Options

replace keeps listed data in memory.

ranks(numlist) restricts tabulation on most frequent sequences.

not(varlist) do not show variables from varlist

exclude0 Restrict calculation of statistics for
egen-erated variables to observations not equal to zero.

listwise is used in connection with exclude0. If
specified, it restricts the calculation of statistics for egen-erated
variables to observations not equal to zero on all variables specified.

list_options are any of the options allowed with list.

summarize_options are any of the options allowed with summarize.

tab1_options are any of the options allowed with tabulate oneway.

tab2_options are any of the options allowed with tabulate twoway.

format(%fmt) specifies output format.

tabsum_options are any of the options allowed with
tabulate, summarize().
