I have one single dataset consisting of the same attributes, but the data describes several hundred groups of different data. The data correlates, but respectively only in each group.
Now I would like to generate a correlation matrix for each group of data automatically and then average the output of all correlation matrices into one single correlation matrix.
If I generate a single correlation matrix out of all the data, there is almost no correlation.
I’m completely new to KNIME, so I’m glad about every hint
Cheers and thanks, Flo
