I am quite new to KNIME. If I have a dataframe like:
Key Old New cor
A 30 40
A 20 15
B 25 30
B 28 65
B 11 19
And I would like to calculate the pearson correlation values of OLD and New these two columns which are grouped by Key. Could anyone teach me with this? Thanks for your time!
Hi Iris,
Thanks for telling me this. However, I need it group by key so I need to know the correlation values of key A and key B individually. Could it be realised in ‘linear correlation’? Thanks.
Best regards,
Runsang
