Correlation Matrix - Export

sherlock

Hello,

how can we export the correlation matrix or the pairwise table of the correlation matrix to Excel?

THANKS!

Hi @sherlock,

You can do this by downloading the coverters extension. 

Extensions | RapidMiner Studio

It has a matrix to example set operator.
Here is the tutorial from the help menu
