Estimate P-values of the Efficient Score Statistics for the Frailty Model

Description

A method to estimate the p-value for the efficient score statistics for the frailty model.

Usage

  PvalueFam(U)  	

Arguments

U	Matrix of contributions of each family to the efficient score statistics of each variable of interest, (i.e., the output from groupedSurvFam).

Value

A data.frame with one row for each variables of interest and four columns: stat, the efficient score statistic, pvalue, unadjusted p-value, FWER, the family-wise error rate adjusted p-value (Bonferroni correction), and FDR, the local false-discovery rate (Storey's Q-value).
