Regression ya vipengele vikuu (PCR)
Regression ya vipengele vikuu kwanza hupunguza seti ya vipambanuzi vilivyounganishwa kuwa vipengele vichache vikuu — mwelekeo wa utofauti mkuu — kisha huweka uhusiano wa kuitikia kwa vipengele hivyo. Kwa kutupa mwelekeo wa utofauti mdogo, PCR huimarisha makadirio mbele ya upotoshaji wa pande nyingi na vipimo vingi, kwa gharama ya kuchagua vipengele bila kurejelea kuitikia.
