MCDMRegression evaluation
R-squared (R²)
Kielelezo cha uamuzi, kilichoashiriwa na R², hupima sehemu ya utofauti katika kigezo tegemezi kinachoelezwa na vigezo huru katika mfumo wa kurudi nyuma. Imeanzishwa na Karl Pearson mwishoni mwa karne ya 19, R² ni mojawapo ya vipimo vinavyotumiwa sana kutathmini jinsi mfumo unavyolingana na data iliyozingatiwa.
