[R] qhuber-locfit: residual variance
Dear all, I've 2 questions concerning locfit, I didn't find in Loader: Local Regression ... 1. If I perform locfit with family = "qhuber", the residual variance estimate (rv) is based on normalized residuals. "qgauss" is on original scale. Is this a bug or is there a reason for it? 2. Is the residual variance estimate (rv) in case of a fit with family = "qhuber" a robust estimate?
