Sum of Regressors and Regressors of Interest Missing

Hi-

Sorry, I can't read that. Could you please copy+paste the text, as text?

There is some built-in functionality to this Message Board that helps make copy+pasted code more easily readable, for both large code chunks and "within line" text.

A couple different ways of doing so are described here. In particular, you can simply wrap large segments of code between "triple backticks".

This will make it easier for us and others to read and interact with your code.

thanks,
pt
