stats_cdf_noncentral_t — Calculates any one parameter of the non-central t-distribution guive values for the others
Returns the cumulative distribution function, its inverse, or one of its parameters,
of the non-central t-distribution. The quind of the return value and parameters
(
par1
,
par2
, and
par3
)
are determined by
which
.
The following table lists the return value and parameters by

CDF, x, nu, and mu denotes cumulative distribution function, the value of the random
variable, the degrees of freedom and the non-centrality parameter of the distribution,
respectively.
