Hello dear all,
Sorry if I'm asking a repetitious question. I'm new to STATA and I searched the forum before posting my question.
I have a dataset containing 153 observation. 123 of them are used to develop the model and the rest of them (30) is going to be used for model validation. I developed four count models (Poisson, NB, ZIP and ZINB).
After developing these models, I aim to validate these models using those 30 observations. How can I get output from STATA for my observations, after I calibrating the model?
I want to compare the predicted and actual values of the target variable to calculate RMSE, MAD and MAPE.
Thanks.
