"How to specify/load/force a linear regression model?"
For my first project, I'm trying to assess an existing model (made several years ago) with a new dataset, and see how its performance is holding up.
However I can't figure out how to load a linear regression model! I can export models generated in RapidMiner to .MOD / XML files and re-load them, but how do I manually enter coefficients and intercepts? I tried kludging my own .XML file by hand, but RapidMiner won't load it.
