Implementation of the Gupta & Liang (1998) formula for computing the probability of correct selection (PCS) for selecting t out of k populations. The results are exact up to a user-settable tolerance parameter. This function is modular and is called by PdofCSt.T1or2, PdofCSt.cyc2, and PofCSGt.

PofCSt(theta, T, m, tol = 1e-07)

`theta` |
Vector of statistics (or parameters) from which it is desired to select the top t of them |

`T` |
The number of statistics (or parameters) desired to be selected |

`m` |
Number of nodes employed in the Gauss-Hermite quadrature |

`tol` |
Tolerance parameter to set the cut-off level for the inclusion of additional probability components in PCS |

The analytic formula for computing PCS for t of k populations is an integral whose integrad is the product of normal densities. This function obtains the appropriate values and computes the integral using a Gauss-Hermite quadrature. See equation 2.4 of Gupta (1998).
