Syntax: PT5(location, scale, shape, stream)
The Pearson type V distribution (continuous) could be used to model the time required to perform some task. The mean and variance are finite only if shape > 2. The Pearson type V distribution is closely related to the gamma distribution - see the book Simulation Modeling and Analysis (Third Edition) by Law and Kelton (2000) for details. Parameter restrictions are scale > 0.0 and shape > 0.0.
Stream allows you to specify the random number stream for the distribution. There are 215 streams. Stream 1 is the default. See Seeds or Appendix D of the User's Guide for more information.
