Subject:      PROC LOGISTIC class statement
Content-Type: text/plain; charset=ISO-8859-1

HELLO:

I have a dataset for which I would like to run my logistic model for three
segments of the data.  Using PROC LOGISTIC I used the following code:

*

PROC* *LOGISTIC* DATA=my3data DESCENDING

OUTEST=BETAS;

CLASS segments;

MODEL y= x1 x2 x3/ LACKFIT RSQUARE CTABLE;

output out=outl p=pred;
*

RUN*;



However, when I go to the output data table BETAS, I do not see a set of
parameters for each one of these segments.  Instead, I only see the
estimates for one model...  Why is this?  And how do I modify the code so
that this model runs three times on one dataset... other than splitting the
dataset out into three datasets and running PROC LOGISTIC 3x?



Thanks!!
