Data Pivot Longer for Discrete Choice Data

Hi everyone!

I have to work with some Discrete Choice Datasets (theory behind this concept for anyone interested) and therefore am trying to familiarize and understand ways to analyze them.

Basically, I want to pivot data from wide format

To long format

I’ve done this with R but I wanted to know if theres a way to do the same with KNIME.

Please share with me the workflows that can enable me to do so using KNIME alone.

Here is the original dataset: Dataset

Heres the paper discussing the dataset and below is the dataset description

Many thanks!
