Correlation is zero
WebOct 30, 2015 · Zero correlation implies independence if the variables are multivariate normal. This is not the same as each variable being normal - see here for some scatterplots of zero-correlated but dependent normal … In statistics, correlation or dependence is any statistical relationship, whether causal or not, between two random variables or bivariate data. Although in the broadest sense, "correlation" may indicate any type of association, in statistics it usually refers to the degree to which a pair of variables are linearly related. Familiar examples of dependent phenomena include the correlation between t…
