If two variables are uncorrelated, there is no linear relationship between them. Uncorrelated random variables have a Pearson correlation coefficient, when it exists, of ...

4 Reasons why Correlation does NOT imply Causation

WebbWe use the integrated relative squared error (IRSE) as a measure of discrepancy between the estimate and the true density because it is more natural to compare this measure across dimensions than the more common ISE. Further, the relative error emphasizes the performance in the tails. WebbIn finance, correlation trading is a strategy in which the investor gets exposure to the average correlation of an index. The key to correlation trading is being able to predict when future realized correlation amongst the stocks of a particular index will be greater or less than the "implied" correlation level derived from derivatives on the index and its single … simple ways to add protein to diet
