Scipy stats beta
WebThe 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) The default p-value returned by pearsonr is a two-sided p-value. Web8 Jan 2015 · import scipy.stats as stats a, b = 500, 600 mu, sigma = 550, 30 dist = stats.truncnorm((a - mu) / sigma, (b - mu) / sigma, loc=mu, scale=sigma) values = …
