7.4.7. mclearn.performance.beta_sum_cdf

mclearn.performance.beta_sum_cdf(x, parameters, res=0.001)

Compute the cdf of the sum of the k beta distributions.

Parameters:

• x (array) – A subset of the domain where we want evaluate the cdf.
• parameters (array of tuples) – Each tuple (alpha_i, beta_i) is the parameters of a Beta distribution.
• res (float, optional (default=0.001)) – The precision of the convolution, measured as step size in the support.

Returns:

y – The cdf evaulated at x.

Return type:

array
