porsBFr {BayesRepDesign}

R Documentation

Probability of replication success based on replication Bayes factor

Description

This function computes the probability to achieve replication success based on the replication Bayes factor. The replication Bayes factor is assumed to be oriented so that values below one indicate replication success, whereas values above one indicate evidence for the null hypothesis.

Usage

porsBFr(level, dprior, sr, paradox = TRUE)

Arguments

level	Bayes factor level below which replication success is achieved
dprior	Design prior object
sr	Replication standard error
paradox	Should the probability of replication success be computed allowing for the replication paradox (replication success when the effect estimates from original and replication study have a different sign)? Defaults to TRUE

Value

The probability to achieve replication success
