Pearson x divergence
In probability theory, an -divergence is a function that measures the difference between two probability distributions and . Many common divergences, such as KL-divergence, Hellinger distance, and total variation distance, are special cases of -divergence.

WebOct 1, 2006 · Kullback–Leibler divergence and the Neyman–Pearson lemma are two fundamental concepts in statistics. Both are about likelihood ratios: Kullback–Leibler divergence is the expected log-likelihood ratio, and the Neyman–Pearson lemma is about error rates of likelihood ratio tests. 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-test. When ρ 0 ≠ 0, the sample distribution will not be symmetrical, hence you can't use the t distribution. In this case, you should use the Fisher transformation to transform the distribution.
