Dear Listers,

I am fairly new to STATA and its model building capabilities so my question
may be naive!

I am trying to replicate a logistic model that I have built in SAS in order
to use the STATA programme: AFLOGIT to calculate the "attributable
fraction".  I am having difficulties with adding three-way interactions to
the model.  The only way I have been able to do this is by using the
"DESMAT" programme.  This allows me to add the three-way interactions but
the AFLOGIT programme no longer works when I use the DESMAT command at the
front of the logistic statement.

Does anyone know of an easier way to add high order interactions to a
logistic model or how I can use the AFLOGIT programme following the DESMAT
statement.

Thanks

Tracy
