K-Means clustering is one of the most widely used unsupervised machine learning algorithms that form clusters of data based on the similarity between … WebThis is the distribution that is used in pearsonr to compute the p-value. The distribution is a beta distribution on the interval [-1, 1], with equal shape parameters a = b = n/2 - 1. In terms of SciPy’s implementation of the beta distribution, the distribution of r is: dist = scipy.stats.beta(n/2 - 1, n/2 - 1, loc=-1, scale=2)
