Improving bias-robustness of regression estimates through projections
We define a robust procedure to "correct" a regression estimate β̂0 along the directions in predictor space where the fit is worse. When β̂0 is the least median of squares estimate, the "corrected estimate" has a smaller maximum asymptotic bias under contamination, and a much bet...
