Hi.
I have two linear regression models A and B:
A:
attribute = c + explanatory_var1
B:
attribute = c + explanatory_var1 + explanatory_var2
Given that I know both explanatory variables are significant, I would like to know a way of testing whether the regression coefficient for explanatory_var1 changes significantly when I add in explanatory_var2.
Does anyone know a test for this that I could perform in STATA?
Many thanks,
Sam.
