Re: st: -ml display- help

the title for the first column of the estimates table after -ml- fits a model.

For single equation models, -ml display- will report the contents of
-e(depvar)- in the column 1 heading provided there are no spaces in
-e(depvar)-. Here is an example do-file:
***** BEGIN:
* xmpl.do
capture program drop mylogit_lf
capture program drop mylogit
program mylogit_lf
version 9.2
args lnf xb
quietly replace `lnf' = ln(invlogit( `xb')) if $ML_y1 == 1
quietly replace `lnf' = ln(invlogit(-`xb')) if $ML_y1 == 0
end
program mylogit, eclass
version 9.2
if replay() {
if ("`e(cmd)'" != "mylogit") error 301
ml display `0'
}
syntax [varlist] [if] [in] [, Level(cilevel) ]
gettoken y xvars : varlist
ml model lf mylogit_lf (`y': `y' = `xvars'), max
ereturn local depvar "AltMessage"
ereturn local cmd mylogit
ml display, level(`level')
end
sysuse auto
mylogit for mpg turn
* end: xmpl.do
***** END:
Here is a portion of the output (notice the 'AltMessage'):
***** BEGIN:
------------------------------------------------------------------------------
AltMessage | Coef. Std. Err. z P>|z| [95% Conf. Interval]
-------------+----------------------------------------------------------------
mpg | -.0752537 .0695708 -1.08 0.279 -.21161 .0611025
turn | -.6226835 .1550278 -4.02 0.000 -.9265323 -.3188347
_cons | 24.51152 6.781471 3.61 0.000 11.22008 37.80295
------------------------------------------------------------------------------
