HI,

 

I have used proc freq with cmh chisq and alpha options to generate odds ratio for my data.

 

Now I need to generate by age category.

 

Can I use class statement?

PROC freq data=mydata;

class agec;

tables trt /chisq cmh alpha=0.05;

RUN;

 

is giving me an error.

 

 

Thanks,

Archana

Here is the documentation for the FREQ procedure. All the valid syntax is explained. There is not a CLASS statement.

 

You can, however, run stratified analyses by using additional variables on the TABLES statement. Here is an example, also from the documentation.

If you simply want separate tests for each age category, sort your data and use a BY statement.

Try

 

PROC freq data=mydata;
tables agec*trt /chisq cmh alpha=0.05;
RUN;
