Extract RapidMiner Linear Regression Model Coefficients

I would like to run a simulation that depends upon Linear Regression Model coefficients.

In RapidMiner, how could I extract the Linear Regression Model coefficients?

I would find it very useful if I could get those coefficients into macro parameters?

Solution

  • It's mildly clunky but it is possible to export the model to a PMML file, read it back in and then parse it using XPath.

    There's an example using decision trees at this link.
