topic Assessing Additive interaction for binary response using linear probability in Statistical Procedures https://communities.sas.com/t5/Statistical-Procedures/Assessing-Additive-interaction-for-binary-response-using-linear/m-p/771198#M37745 <P>I am trying to figure out what distribution would be the most appropriate. My professor said to model the log regression as a linear probability to assess for additive scale. I didn't find statically significant interaction when using link=identity distr=bin, but when I stratified by the suspected effect modifier, I could see a difference. When I went back and changed the distr=bin to distr=normal, it displayed significant interaction. She said I could do it, but this doesn't make sense to me because the response variable is binomial. Could someone explain?</P> Wed, 29 Sep 2021 18:45:42 GMT Kaeslock223_ 2021-09-29T18:45:42Z Assessing Additive interaction for binary response using linear probability https://communities.sas.com/t5/Statistical-Procedures/Assessing-Additive-interaction-for-binary-response-using-linear/m-p/771198#M37745 <P>I am trying to figure out what distribution would be the most appropriate.
