trying to do a robudt regression of a two-way linear model, I keep getting the following error:
> lqs(obs ~ y + s -1,method="lms", contrasts=list(s=("contr.sum")))
Error: lqs failed: all the samples were singularRobust regression with M-estimators works (also regular least square fits, of course):
rlm.formula(formula = obs ~ y + s - 1, method = "M", contrasts = list(s = ("contr.sum")))
I tried an exact sampling (psamp="exact"), but I keep getting syntax errors. Any idea how I can make the first one work?
Thanks,
joerg
