Subject: Zero inflated Models- pscl package
Dear R users,
I want to apply zero inflated models with continuous and categorical
variables and I used pscl package from R and the zeroinf() function. My
question are the follow:
a) The value of fitted.values is mu or (1-p)*mu? where p is the probability
of zero came form a zero point mass
b) If mu is zero, how do i know if it is a zero from the zero point mass or
from the count process?
Thank you so much in advance.
Filipa J.
