Minimizing Oblique Errors for Robust Estimating
Diarmuid O’Driscoll, Donald E. Ramirez, Rebecca Schmitz · Irish Mathematical Society Bulletin · 2008
The slope of the best fit line from minimizing the sum of the squared oblique errors is shown to be the root of a polynomial of degree four.We introduce a median estimator for the slope and, using a case study, we show that the median estimator is robust.
