getting the linear regression results as an output

KNIME Analytics Platform

Hi

I’m looking at the linear regression learner, and would like to get the data the View: Linear Regression Results View - namely the statistics like R-square etc as an output which can be processed. Is there a way to do this? Currently I can only see it as a View. The Coefficients and Statistics output port does not return the statistic for the fit, but only the statistics of each coefficient and intercept.

Thanks

David

As far as I can tell, the way to get a table displaying an R-squared value would be to evaluate your model using test data with the Regression Predictor node, and then score the model using the Numeric Scorer node.

Thanks for the reply.

What a shame if that’s the case, as the value is already present.

Anyone from KNIME who can say if this is the only way?

Followed your advise and did the calculation as suggested. Thanks.
