Hi
I am working on a panel data, my data are clustered/grouped by the variable
"yearctry", I am running the regression below, but I cant make the
regression recognise "yearctry" as the panel variable in the regression

myProbit<- glm(s ~ age + gender + gemedu + gemhinc + es_gdppc +
    imf_pop + estbbo_m, family = binomial(link = "probit"), data =
adpopdata)

Can anyone help me do this please???

Thanks
Saurav
