Uncorrelatedness (probability theory)
text:
In probability theory and statistics, two real-valued random variables, X , Y , are said to be uncorrelated if their covariance, cov [ X , Y ] = E [ X Y ] − E [ X ] E [ Y ] , is zero. If two variables are uncorrelated, there is no linear relationship between them. Uncorrelated random variables have a Pearson correlation coefficient, when it exists, of zero, except in the trivial case when either variable has zero variance. In this case the correlation is undefined. In general, uncorrelat
