Title

    sum2 -- Store summary statistics suitable for use with table-making


Syntax

    sum2 [, options]


Description

    sum2 provides a fast and easy way to store summary statistics for use
    with standard table-making programs such as outreg, outreg2,
    estimates_table, xmltab, etc.

    sum2 was motivated in part by mfx2 and margeff that do the same thing
    for marginal effcts.

    sum2 will only report for variables and observations used in the last
    regression command. Therefore it will work only after a regression
    has run.

    More specifically, sum2 will store the mean in e(b) matrix and the
    cross-product of the std. dev. in e(V) matrix.



Options

    replace the stored estimates is replaced with summary stats. This is
            a reminder that you are getting rid of the previously stored
            estimates.


Examples

    * use with outreg2
    sysuse auto, clear
    reg mpg headroom length rep78
    outreg2 using myfile, replace
    sum2, replace
    outreg2 using myfile, see noaster

    * use with original outreg
    sysuse auto, clear
    reg mpg headroom length rep78
    sum2, replace
    outreg using myfile.txt, replace nonote noaster
    type myfile.txt


Issues

    Matsize limitations may bite if there is a large number of variables.
            Try increasing matsize in that case.
