One minus pearson correlation
Web02. jun 2016. · 1 Answer Sorted by: 8 The module scipy.spatial.distance implements the "correlation distance", which is simply one minus the correlation cofficient. You can use the function cdist to compute the one-to-many distances, and get the correlation coefficients by subtracting the result from 1.

WebIn statistics and in probability theory, distance correlation or distance covariance is a measure of dependence between two paired random vectors of arbitrary, not necessarily equal, dimension. The population distance correlation coefficient is zero if and only if the random vectors are independent. WebThe correlation distance is simply equal to one minus the Pearson correlation between vectors. Mathematically, it is equivalent to the cosine distance between the vectors after …
WebThe correlation ranges between plus and minus one. When ρ is used as a descriptive statistic, no special distributional assumptions need to be made about the variables (Y and X) from which it is calculated.
