I have acquired count data with an excess amount of zeros. Therefore, I
have employed the zero-inflated poisson model.
My main interest is to visualize the interaction between a categorical
value (0/1) and a continuous variable. My model also contains a few
covariates.
I have tried to apply the prvalue command, however I always run into a
conformability error r(503). I have checked my data, and I have no missing
values.
I have also tried to use the margins command, but it doesn't seem to
work because my continuous variable is a not an integer.
Does anyone have any other suggestions on what I can do?
Thank you,
Elizabeth
