sensitivity analysis

[floflow]

Hi,

I am currently doing multi-level-regressions, looking at the link between sleep and social media use. 

proc surveylogistic data=sleep; *unadjusted;
cluster id2;
class smu (ref='active');
model sleep_rec (event='not meeting sleep recommandations') = smu;
weight wtcan;
run;

I want to add sensitivity analysis to see if there are gender differences in different social media use categories. 

I have no idea where to start. 

Thank you so much

How about this:

proc surveylogistic data=sleep; *unadjusted;
cluster id2;
class smu (ref='active') gender;
model sleep_rec (event='not meeting sleep recommandations') = smu gender smu*gender;
weight wtcan;
run;

That works!
Thank you so much!
