PofCSLt.bootstrap5 | R Documentation |

Parametric bootstrap for computing L-best PCS. This function is called by the wrapper PCS.boot.np.

PofCSLt.bootstrap5(theta, T, L, B, SDE, dist = c("normal", "t"), df = 14, trunc = 6, est.names = c("O"))

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

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

`L` |
Vector of L-best selection parameters |

`B` |
Bootstrap sample size |

`SDE` |
Standard error of the statistics theta (row-wise) |

`dist` |
Distributional assumption used for estimating PCS |

`df` |
Common degrees of freedom for one of the t-statistics in theta; the parameter is only used if dist="t" |

`trunc` |
Number of standard errors below the minimum selected population to disregard in the estimation of PCS; it is a truncation parameter to decrease run time |

`est.names` |
Kind of shrinkage estimator employed. Default estimator is "O" for the Olkin estimator. Other estimators will be considered for future releases. |

An array, the non-empty part of which is a matrix whose rows are the entries of L and whose columns are the entries of T.
