Description
|
|
•
|
The noncentral beta distribution is a continuous probability distribution with probability density function given by:
|
|
subject to the following conditions:
|
•
|
The NonCentralBeta variate with noncentrality parameter delta=0 and shape parameters nu and omega is equivalent to the Beta variate with shape parameters nu and omega.
|
•
|
Note that the NonCentralBeta command is inert and should be used in combination with the RandomVariable command.
|
|
|
Notes
|
|
•
|
The Quantile and CDF functions applied to a noncentral beta distribution use a sequence of iterations in order to converge upon the desired output point. The maximum number of iterations to perform is equal to 100 by default, but this value can be changed by setting the environment variable _EnvStatisticsIterations to the desired number of iterations.
