st: Predict Command after zinb
I am trying to understand how the predict command
works after zinb command. I want to know if we can use
generate command to get the same result as predict
For example, if we run nbr and then run predict
command, we can get the same results with the
generate command using the beta coefficients and then
generate abs= Constant + b1x1 + b2x2 + b3x3
generate eabs= exp(abs)
The eabs values are same as the estimated values using
the predict command.
However, I am not able to get the same results with
zinb. I think this is mainly due to the two part
solution ( the always zero group and not always zero
Does anyone have any thoughts on how to get the same
results as predict command using generate?
