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