  • -vcemway logit- and city year effects

    Hello, Statalist
    I need your help for two questions.
    1. In Stata, if we use -vcemway logit- and cluster city and year, can we also include -i.city i.year- in the command?
    I try to run it in Stata. There is no result. However, if I replace -i.city- with partial cities, city01-city120. Stata can get result.
    I am not sure whether this kind of combinations make any sense econometrically.
    2. The reviewer asks me to include both city and year effect in the estimation. I did that with simple -logit- including -i.city i.year-. However, I encounter perfect collinearity and get no result from Stata. Any suggestion I can solve the problem?
    Thanks in advance.
