Regression Imputation for missing value

[shru]

Hi All,

I want to know how to do missing value imputation using “Regression Imputation” in KNIME. Which node should be used to do it?
Need your help on the same.

Thanks.

Hi @shru,
I have created an example workflow for you. Does that help?

To add here, I took a look and had to fill the missing values first before the learner. Otherwise it returns an error for me.
Great solution @AlexanderFillbrunn

Thanks @Daniel_Weikert,
That’s what you get for simply ripping out a part of a workflow and then not testing it again. I fixed it in the workflow on Community Hub by setting the Linear Regression Learner to ignore rows with missing values. Quick&Dirty
Kind regards,
Alexander
