What mean of model_diagnostics

Hi, I don’t know what means of the command “model_diagnostic”, and why and when we need to use it. Thanks a lot.

It checks your model for the presence of obvious problems (missing variables, wrong timing, collinearity). It is always a good idea to run it on your model to see if anything pops up.

Thanks a lot. Professor jpfeifer, I really appreciate your kindness.
