missing fileds in correlation matrix

[neelu kat]

Hi all,

I created a correlation matrix for 4 columns and 60 rows data, but I got the matrix with negative values as -1 and some fields have missing values, when I import excel sheet to rapid miner, I have question marks in missing fields. Please advice.

Thanks
