In sjpierce/piercer: Functions for Research and Statistical Computing

Convert p-values into s-values, Bayes Factor Bounds, and posterior probabilities that H1 is true

Description

This function converts p-values into three different measures: s-values, Bayes Factor Bounds (BFBs), and posterior probabilities that the alternative hypotheis H1 is true.

Usage

convertp(p, digits = NULL)

Arguments

p	A numeric p-value (or numeric vector of p-values), obtained from running a statistical model or test. All values should be proportions within the closed unit interval (0 <= p <= 1).
digits	An integer specifying the number of decimal places to used when rounding the results. Defaults to NULL, which does not round the results.

Details

=============================================================================

This function applies p2s, p2bfb, and p2pp to the p-values supplied. It is a convenient way to get all three results with a single function call.

Value

A data frame containing three numeric columns values, each the same length as p: s-value, BFB, and posterior probability.

Examples

convertp(.05)
convertp(c(.1, .05, .01, .005, .001, .0001, .00001), digits = 2)
convertp(p = NA) # Missing p returns a missing value.
