Parameters
Parameters 
Description 
p 
Probability, real positive value on closed interval [0,1]. 
Mu 
Defines distribution Mu parameter. Mu must be a positive scalar. 
Lambda 
Defines distribution Lambda parameter. Lambda must be a positive scalar. 
Returns

the inverse Gaussian distribution point percent function (PPF) for probability p using the parameters Mu and Lambda. Probability p must lie on the interval [0,1] and Mu, Lambda must both be positive, otherwise the result is NAN.

Description

The inverse CDF is defined by the following equation:
