The study is concerned with solving the problem of the negative variance concerning the (GLS) method and hence a comparative study of (GLS) and GMM procedures with Simple Panel Data (SPD) and Multiple Panel Data (MPD) is introduced and discussed simulated data from several models that used to compare the two procedures under different conditions of panel data such as : ample sizes , models , parameters values and standard deviation



Generalized least square Generalized method of moment Simple Panel Data
