Hello
I have a data set with outlier and it is not normally distributed. I would
instead like to use a more robust distribution like t-distribution.
My question is if the coefficients of the regression are different from zero,
but assuming a t-distribution.
Could someone hint me what package to use or....
Have you considered using a robust method?
There's rlm() in MASS, lmrob() in robustbase, etc.

Thanks in advance
