I have the following code for my logistic regression. However, I need to add industry fixed effects, year fixed effects with dummy variables. Could someone help me with this?
Thank you very much in advance.
Proc logistic data=Exam.Alltables
class High_sensitive (param= ref ref=' No ') EPA (param=ref ref='No ') Emissions_trading (param=ref ref='No ') ;
model disclosure (event= '1 ')= High_sensitive Div_emissions EPA Emissions_trading Assets_LN /

Thanks for your answer. I tried with the statement strata but all the dummy variables are dropped because of redundancy.
I am trying to build a longitudinal data for 4 years in order to determine whether companies disclose non financial information in the annual reports. Independent variables: sensitive industris, regulation, etc.
