"Logistic Regression PMML"

hi,

Should I be able to write PMML for a regular (non-evolutionary) Logistic Regression model? I get an error stating "The class MyKLRModel cannot be exported to PMML" regardless of whether kernel type is set to dot or not.

If not, is this a limitation of PMML or RapidMiner? ie could I manually write PMML to match a Logistic Regression generated by RapidMiner?

And by the way, the Write PMML operator does work if I use Evolutionary Logistic Regression and set the kernel type to dot. The results are much worse though.

thank you,
Ben

Hi Ben.

You are right.
Currently you can't write a PMML file for your data using logistic regression with a specific kernel other than dot.
Thats because you simply cant switch the kernel type in a PMML file. You can take a look to the LogisticregressionPMMLWriter class in die PMML plugin.

This limitation is more a PMML limitation. http://dmg.org/v4-1/Regression.html explains very well whats possible and how its done.
