Function Reference: bisacdf

statistics: p = bisacdf (x, beta, gamma)
statistics: p = bisacdf (x, beta, gamma, "upper")

Birnbaum-Saunders cumulative distribution function (CDF).

For each element of x, compute the cumulative distribution function (CDF) of the Birnbaum-Saunders distribution with scale parameter beta and shape parameter gamma. The size of p is the common size of x, beta and gamma. A scalar input functions as a constant matrix of the same size as the other inputs.

p = bisacdf (x, beta, gamma, "upper") computes the upper tail probability of the Birnbaum-Saunders distribution with parameters beta and gamma, at the values in x.
