Dear all,
I am trying to run the following regression:
where count_00_05, count_05_010, count_10_13,...count_g37 are variables that count the number of times temperature occurs in a certain bin. When I run this regression, Stata automatically drops a bin (because they are perfectly collinear) but it does so arbitrarily. Is it possible to specify the bin to be dropped (as reference category)?
Even when I drop one myself, Stata drops another one from the the bins included.
I would be grateful for any suggestion. Thank you.
Sincerely,
Chiara
