Have just checked with R 3.2.0 and MASS 7.3-40 and there still appears to
be a problem/strangeness at around k=2.5

Dear all,
I believe I have found a bug in rlm in the MASS package. Specifically, the
scale estimate can be wrong when there are no outliers. The following code
snippet is an example:
dose <- c(0,1,2,0,1,2)
response <- c(0.659,1.633,3.621,1.803,3.093,4.424)
line <- c(1,1,1,2,2,2)
k2 <- seq(1.5,5
2 matches
