Testing the coefficients of different models

[Florian Degrave]

Dear

I need to test whether two coefficients of the same variable in different models are significantly different from each other. I wanted to do this by using the test command. You can see my stata output below;

regress v2 v1
est store m1

regress v3 v1
est store m2

test [m1]v1 = [m2]v1

After running my code, I get an error message: 'equation m1 not found'

Can someone provide me a solution?
