Coefficient as legend in graph??

[Anna Stubbendorff]

Hi!

I there a way to insert a coefficient from the linear regression as legend in a graph? In this case, 0.0309 (rounded with two decimals) and 0.351... from the multivariate regression.

coefplot is from SSC, as you are asked to explain in FAQ Advice #12.
