Mbinu ya Viwango Vidogo Vilivyopanuliwa (GLS)
Mbinu ya Viwango Vidogo Vilivyopanuliwa (GLS) ni njia ya makadirio ya urejesho wa mstari inayopanua mbinu ya viwango vidogo vya kawaida (OLS) kushughulikia hali ambapo vipengele vya makosa vina uhusiano au vina utofauti usio sawa (heteroscedasticity). Imeanzishwa na Alexander Craig Aitken mwaka 1935, GLS hupata Makadirio Bora ya Mstari Yasiyo na Upendeleo (BLUE) chini ya muundo wa jumla wa kovariansi ya makosa kwa kuweka uzito kwa uchunguzi kulingana na usahihi wao, ikitoa daraja la kinadharia kati ya OLS na mifumo ya kisasa ya mchanganyiko wa mstari.
