hi aswin bro, values more than 0.05? or more than 0.5 corr dependies with each other? @9.05 sec

[@HackersRealm]

it depends on the range, if it's closer to 1, it's highly correlated,, if it's in middle like 0.5, there is medium correlation, etc.,

HI Aswin bro, what does it meant the term you used "its leaking the data" @4.48 sec.

[@karthikrajendran3394]

What should we do with -ve correlated columns?

[@HackersRealm]

positive and negative both are to be considered which is at extremes.
