I am sorry about the confusing subject in my previous email. Here's the one
I intended to put
Dear Statalisters,
I have a simple question, but that I haven't been able to answer for some
time...
I have a bilateral trade (gravity) model, with pairs of countries as
individuals. I want to estimate a model in cross-section that includes
country fixed effects, but have not been able to control the dropping of
some of these effects.
Does anyone know of any command to tell STATA how to prioritise the dropping
of collinear variables?
Any suggestions/ideas will be more than welcomed!
