I want to know more about ridge regression in stata. I
actually am working with some data that seems to be
highly multicollinear. I looked up the literature that
ridge regression could be onne way to estimate the
pareameters.
I am tryinf the dollowing command
rxridge y x1 x2 x3
in my case it terminates with the following message.
RXridge: Shrinkage Coefficients...
obs was 0, now 25
(18 missing values generated)
(note: file rxridge1.dta not found)
file rxridge1.dta could not be opened
r(603);
This might be a very dumb question but I will be very
grateful for a response.
Thanks
Sri
