Thanks for your help.

panel estimation with TSLS
Dear All, I am estimating a panel regression with TSLS and whenever I include either fixed effects or time dummies I get the following error message: "positive or non-negative argument to function expected". Could anyone help me? Please see equation1 in the attached file (forum.wf1). Thank...
