...(3). To start with I would like to make sure that I
got the output from (3) right. The ouput of (3) tells me that the highest
R^2 value was reached after 8 iterations and there are only 8 significant
predictors in this model ??? In addition the only significant frequencies
(predictors) left are:
cos1, cos2, cos4, cos7, sin1,sin2, sin3, sin5
I got this information interactively. But I'm in troubles at extracting it
automatically.
Any suggestion ?
Question: Do I have to run "step" in advance of "regsubsets" for a
first-pass model pruning or may I run "regsubsets&qu...
