Help with Regression Interaction Term Command

[Jason Browen]

Dear all,

I am using Stata 16, on mac. I need help estimating the following model

Where educ_i x urban_i is an interaction term


I used the command: regress wage educ urban i.educ i.urban, but I am not sure if it is correct.


I would greatly appreciate it if someone could check to see if my command is correct.


Thank you in advance for your help

This sounds like a homework exercise to me. So I am not going to give you the full answer, not because I am mean (I may very well be), but because figuring this stuff out is part of the learning experience. All I am going to give you is a place to start, and that is: type in Stata help fvvarlist

I'm quite happy to give you exactly what you asked for. I've checked your "command" to see if it is correct. It is not.

Jason:
in all likelihood, the regression model you were requested to estimate suffers from endogeneity (see https://www.stata.com/bookstore/micr...metrics-stata/, Chapter 6).
