A feasible generalized least squares (GLS) \nprocedure is proposed as a weighted least squares that \ncan handle a wide range of unequally spaced panel data \npatterns. This procedure is simple to compute and provides \nnatural estimates of the serial correlation and variance \ncomponents parameters.
