Central MVTDistribution
class CentralMVTDistribution(dof: Double, covariances: Array<DoubleArray>, stream: RNStreamIfc = KSLRandom.nextRNStream()) : CentralMVNDistribution
Represents a multi-variate t-distribution with means = 0.0 and the provided covariances. The computed CDF values are to about 2 decimal places using Monte-Carlo integration
Parameters
dof
the degrees of freedom, must be greater than zero
covariances
the variance-covariance matrix, must not be null, must be square and positive definite
stream
the stream for the sampler
