estP0: Estimate the fraction of true null hypotheses.

In CenterForStatistics-UGent/reconsi: Resampling Collapsed Null Distributions for Simultaneous Inference

Estimate the fraction of true null hypotheses.

Description

Estimate the fraction of true null hypotheses.

Usage

estP0(statObs, fitAll, z0quantRange, smooth.df, evalVal, assumeNormal)

Arguments

statObs	A vector of observed z-values
fitAll	the estimated normal null
z0quantRange	a number of quantiles between 0 and 0.5
smooth.df	degrees of freedom for the spline smoother
evalVal	the value of q at which to evaluate the spline
assumeNormal	A boolean, should normality be assumed for the null distribution?

Details

A natural spline is used over a range of intervals. Based on the qvalue::qvalue() function and Storey and Tibshirani, 2003

Value

The estimated null fraction, the value of the spline evaluated at the first element of z0quantRange
