This paper examines general variance-covariance structures for the specific effects and the overall error term in a twoway random effects (RE) model. So far panel data literature has only considered these general structures in a one-way model and followed the approach of a Cholesky-type transformation to bring the model back to a "classical" one-way RE case. In this note, we first show that in a two-way setting it is impossible to find a Cholesky-type transformation when the error componentsdoi:10.4236/am.2013.44086 fatcat:btfqk4mj7za2fjyrpxnajpwilm
