sciPy stats.bayes_mvs() function | Python

scipy.stats.bayes_mvs(arr, alpha) function computes mean, variance and standard deviation in the given Bayesian confidence interval.

Parameters : arr : [array_like] The input data can be multidimensional but will be flattened before use. alpha : Probability that the returned confidence interval contains the true parameter. Results : mean, variance and standard deviation in the given Bayesian confidence interval.
