KNIME prediction using polynomial regression model

I need to calculate predictions for the daily maximum per 30-minutes load from 1 January to 31 January and I need to save those predictions to resultsXX.csv. I already have the knimw workflow done I just can’t get the predictions! Can anybody help me?

Hi @Fcp1893 and welcome to the forum. You should be able to use the CSV Writer node for this. If you need more help, feel free to post your workflow and we can try to get into the details.

My main issue is using the data of 2014 and 2015 to make a prediction for January 2016.
How can I make this?
Maybe I can send you an email with my workflow? It would be great if you could help me! Thanks

You can post your workflow on forum. Just drug and drop it in the window.

Hi there @Fcp1893,

if you wanna upload workflow first export it and then either drag&drop it or follow same procedure as for uploading images.


In that case you could use a Row Splitter node, using the range checking option, to separate your 2014-2015 training observations from your 2016 testing observations.

As Ivan and Igor have suggested, if you could upload your exported workflow as a KNWF file - as opposed to just screenshots - that would be helpful.
