While I am running regression in Stata, many times a variable is dropped due to collinearity. In the model results, the variable shows a 0 coefficient. When I am checking the correlation between the variables in the models, the omitted variable does not have a very high correlation with any of the variables. Any explanations to this phenomenon?
