Dear Stata Community,

I am looking for the right statistical model to test hypotheses with the following:
Independent variable: Count data on level of US states, e.g.: Michigan=304. and of US ZIP codes, e.g. 98661=1.
Dependent variables: Continous but NOT normally distributed, negative and positive values. E.g. Return of assets.
Eventually I will also need to consider some control variables.

Best,

Thomas
