20200624 Pikairos Correlation between columns

I want to keep on my data only the highly correlated variables to the first column (my actual dependent variable). Is there any way to accomplish that?
For ex: My first column is the dependent variable (named: Y) and all the other ones are independent ones. I’m trying to establish a threshold of only the X variables correlated (>0,3) with the first one, and the rest filtered out of the data.
