Regression lineara
Una regression lineara es un modèl de regression qu'assaia d'establir una relacion lineara entre una variabla, dicha « variabla explicada », e un ensemble d'autrei variablas, dichas « variablas explicativas ». Apareguda vèrs 1755 dins lei trabalhs de Ruder Josip Boskovic (1711-1787), aqueu metòde es fòrça eficaç per construrre un modèl de prediccion d'un fenomèn. En revènge, es pauc adaptat a la cèrca d'una explicacion car permet pas, ò pauc, de comprendra la natura deis interaccions que lo definisson. La regression es donc fòrça utilizada en engenhariá.
