Dear Stata-listers,

I am very thankful to Nick Cox for putting together "makematrix". I have
tried it to save and return the AIC and Schwarz's Criterion from a few logit
models and his suggestions worked well.

It will helpful to me if I can first obtain a matrix of the "Odds Ratio z
P>|z| [95% Conf. Interval]" produced by "logistic" but I am not sure to
which global macros S_E_** are those saved (I have had a look through
logistic.ado, logistic.dlg,logis_lf.ado).

I guess I am looking at a 3-step process:

1. a do-file is first saved as "mydo1.do" containing one command line
		xi : logistic lbw i.`1'

2. a second do-file "mydo2.do" is saved containing two command lines
		xi : logistic lbw i.`1'
		mlfit 

3. Then the command lines below run to obtain the two matrix outputs:

	makematrix, from(S_E_**): "run D:\mydo1" stunt3 stunt6 stunt12

	makematrix, from(S_E_aic S_E_sc): "run D:\mydo2" stunt3 stunt6
stunt12


Many thanks for your help in advance.


Amani
