Pearson correlation method

WebThe Pearson correlation coefficient measures the linear relationship between two datasets. Like other correlation coefficients, this one varies between -1 and +1 with 0 implying no correlation. Correlations of -1 or +1 imply an exact linear relationship. ... The object has the following method: confidence_interval(confidence_level=0.95) WebNov 20, 2014 · The Pearson correlation coefficient relies on estimating means and (co)variance. Infinite values lead to infinite means and infinite variances, which break computations. Spearman and Kendall correlation coefficients are rank-based, and thus handle sorting just fine with infinite values (but beware of tied values in your samples!).. …
