Description Usage Arguments Value

View source: R/robustregression.R

Description

This uses Huber's psi to estimate a robust least squares fit, while at the same time using Schweppe weights to downweight leverage points in the design matrix. The algorithm is initialized using Pena-Yohai initial S-estimates.
