Regression Imara (Robust Regression)

Regression imara hutoa makadirio ya uhusiano wa mstari kati ya matokeo yanayoendelea na vigezo vya utabiri huku ikipunguza kwa kiasi kikubwa athari za vipengele vya nje (outliers) na pointi za mvuto (leverage points). Tofauti na OLS (Ordinary Least Squares), ambayo huathirika sana na uchunguzi wa kipekee, mbinu imara hupeana uzito mdogo kwa pointi za data zisizo za kawaida, na kutoa makadirio ya mgawo (coefficient estimates) ambayo hubaki thabiti hata pale ambapo sehemu ya data imechafuliwa au haijasambazwa kwa kawaida.
