pbeta

The beta cumulative distribution function

Calling Sequence

F = pbeta(x,a,b)

Parameters

x

matrix (elements between 0 and 1)

a,b

positive reals, parameters of the beta distribution(x,a,b can be scalar or matrix with common size)

F

matrix

Description

for each element of x, F=Prob(X<x) where X is a random variable with beta density

x.^(a-1) .* (1-x).^(b-1) ./ beta(a,b)1_{0<x<1}
