pval_percentile {rbmi}

P-value of percentile bootstrap

Description

Determines the (not necessarily unique) quantile (type=6) of "est" which gives a value of 0 From this, derive the p-value corresponding to the percentile bootstrap via inversion.

Usage

pval_percentile(est)

Arguments

est

a numeric vector of point estimates from each bootstrap sample.

Details

The p-value for H_0: theta=0 vs H_A: theta>0 is the value alpha for which q_alpha = 0. If there is at least one estimate equal to zero it returns the largest alpha such that q_alpha = 0. If all bootstrap estimates are > 0 it returns 0; if all bootstrap estimates are < 0 it returns 1. Analogous reasoning is applied for the p-value for H_0: theta=0 vs H_A: theta<0.

Value

A named numeric vector of length 2 containing the p-value for H_0: theta=0 vs H_A: theta>0 ("pval_greater") and the p-value for H_0: theta=0 vs H_A: theta<0 ("pval_less").
