The distance metric is: d = 1 − tr ( R 1 ⋅ R 2) ‖ R 1 ‖ ⋅ ‖ R 2 ‖, where R 1 and R 2 are two correlation matrices and the norm is the Frobenius norm. This metric take values from 0 (identical matrix) to 1.

WebIndeed, Cohen (1988) developed this concept. The effect size is a quantity that will allow to calculate the power of a test without entering any parameters but will tell if the effect to be tested is weak or strong. In the context of comparisons of correlations conventions of magnitude of the effect size are: Q=0.1, the effect is small. WebTests. When the null assumption is ρ 0 = 0, independent variables, and X and Y have bivariate normal distribution or the sample size is large, then you may use the t … WebCorrelation =-0.92 Analysis: It appears that the correlation between the interest rate and the inflation rate is negative, which appears to be the correct relationship. As the interest rate rises, inflation decreases, which … dc motor hacks
