brxx_ICC_general: brxx_ICC_general: Bayesian Estimation of Reliability from ICC, General Form

Description

This function estimates reliability from intraclass correlation given correlation.

Usage

brxx_ICC_general(WS, Resid, alpha, beta, CI, items)

Arguments

WS

Within subjects variance estimate.

Resid

Residual variance estimate.

alpha

Prior true score variance.

beta

Prior error variance.

CI

Credible interval quantile, as a decimal (ie, for 95 percent, 0.95).

items

Number of test items.

Value

Returns estimated median and quantile based credible limits for reliability.

Examples

# NOT RUN {
WS=20.4
Resid=3.6
alpha=3.51
beta=1.75
