[R] Zero inflated Models- pscl package

[Filipa J.]

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.
