Internal nFDR Functions

Description

Internal nFDR functions.

Usage

Bf(f, k, x)
hk(R,k)
F.tilde(tt,x,n)
f.tilde(tt,x,n, Smooth = TRUE)

Arguments

x a vector of p-values
R vector of r values
f vector of sampled value of function f
k order of Bernstein polynomial approximation
n order of Bernstein polynomial approximation for cdf F or pdf f
tt vector of values on [0,1] at which Bernstein approximation are evaluated
Smooth default is TRUE, F is smoothed first

Value

Function bf returns Bernstein approximation of function f based on sampled values given in argument f. Function hk returns value of h(r,k) used in calculation of the variance of the estimator tilde_pi_0 of π0. Function F.tilde returns values of Bernstein approximation F_tilde of cdf F. Function f.tilde returns values of Bernstein approximation f_tilde of pdf f with sampled values of f is numerically estimated by F, if Smooth = FALSE, or by F_tilde.
