pool object in a system
Posted: Tue Aug 13, 2013 10:15 am
I want to run a nonlinear ls regression for a pooled cross section time series data. I created a pool object. I think the only way to run nonlinear regression for this data is a system object. When I use varname_? in the system object, it says it is not defined. How do I define it? Pool is already in my workfile.
