Dear colleagues, I would like to ask you how to estimate biweight M-estimator of Tukey with known scale example.
I know how to estimate biweight M-estimator if estimated scale is used using function rml in package MASS. library(MASS) x<-rnorm(1000) rlm(x~1,psi="psi.bisquare") But I would like to estimated this with true scale s=1. I also checked package robustbase, but I have not found any solution. Thanks for any advice.
