Multiple binary outcomes

Hello Forum,

I was wondering if  there is way to model multiple binary outcomes in SAS?

Thanks !!!

Re: Multiple binary outcomes

Your question is kind of sketchy. You may get more useable responses you provide some example data and what your are trying to do.

Re: Multiple binary outcomes

Hi ballardw,

In MANOVA (Multivariate Analysis of Variance) we can fit multiple dependent variables but they have to be continuous .  Here I am trying to model multiple (alcohol, smoking, drug)  binary (0/1) outcome with some set of predictors .  Proc Logistic can handle only one dependent variable.  I don't  know if there is multivariate counterpart of proc logistic.

Here is mock data.

DATA;

INPUT ALCOHOL SMOKE DRUG  GENDER $  RACE   $;

CARDS;

1  0  1  MALE    WHITE

0  1  0  FEMALE  HISPANIC

1  0  1  MALE    BLACK

RUN;

Thanks !!!

PROC CATMOD presents some possibilities. Start with Example 32.4 Log-Linear Model, Three Dependent Variables, and work up from there.

See the "Multivariate logistic model" item the following note:

   http://support.sas.com/kb/22871

Not quite the log-linear model that Steve mentioned, you could use CATMOD with the RESPONSE LOGITS; statement when specifying multiple response variables.  The note also mentions QLIM for the bivariate case.
