rvalueBoot {rvalues}R Documentation

Bootstrapped r-values

Description

Estimates a new prior for each bootstrap replications ... (need to add)

Usage

rvalueBoot(object, statistic = median, R, type = "nonparametric")

Arguments

object

An object of class "rvals"

statistic

The statistic used to summarize the bootstrap replicates.

R

Number of bootstrap replicates

type

Either type="nonparametric" or type="parametric"; the nonparametric type corresponds to the usual bootstrap where units are sampled with replacement.

Details

When type="nonparametric", the prior is re-estimated (using the resampled data) in each bootstrap replication, and r-values are re-computed with respect to this new model.

When type="parametric",

Value

A list with the following two components

rval.repmat

A matrix where each column corresponds to a separate bootstrap replication.

rval.boot

A vector of r-values obtained by applying the statistic to each row of rval.repmat.

rv <- rvalues(dd, family = gaussian, prior = "conjugate")

rvb <- rvalueBoot(rv, R = 10)
