interaction categorical with categorical glimmix estimate statement

jomag — Tue, 10 Dec 2019 23:31:23 GMT

hi everyone,

I want to calculate the effect estimate of my 4-level categorical variable when my two-level categorical variable =1 and when the two-level categorical variable=2 in proc glimmix.

However, I am not sure of my estimate statement, and I'd appreciate any input or help on how to write this interaction estimate statement.

Below is my current SAS code:

proc glimmix data=data method=quad(qpoints=50) inititer=5;

class id var1 var2 var3 ;
model outcome = var1 var2 var3 var1*var2 / link=log solution dist=nb offset=log_PY;
random int / subject=id;

estimate 'n vs h' var1 1 0 0 -1/exp cl;
estimate 'l vs h' var1 0 1 0 -1/exp cl;
estimate 'm vs h' var1 0 0 1 -1/exp cl;

estimate 'var1 when var2=1' 

var1 1 0 0 -1
var1*var2 1 -1 /exp cl;

estimate 'var1 when var2=2' 

var1 1 0 0 -1
var1*var2 -1 1 /exp cl;


run;

Thank you.

Use the SLICE statement.
