Hey there.
I am running a multiple regression and want to see whether a robust
regression would provide different results, since there is some
heteroscedasticity and other minor violations of regression assumptions.
When I run the model using the robustbase package,
> modelrob=lmrob(m1)
I receive the following error:
> Error in qr.default(x * sqrt(ret$weights)) :
> NA/NaN/Inf in foreign function call (arg 1)
Google wasn't helpful, maybe you can help me out. If this problem is not
obvious to someone who uses R regularly, please let me know what further
information to provide.
Thank you!
