Dear all,
I have a problem with gamma regression (glm - family = Gamma) and zeros in R.
The problem is the following when I try to estimate a dataset without zeros
(endogenous variable) there is no problem. However, if I try to do the same
with zeros I always get an error message. In STATA and MATLAB I can do a gamma
regression with zeros. What could be the problem? If someone could help me I
would really appreciate this.
Thanks in advance, Soeren
