In brxx: Bayesian Test Reliability Estimation

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

WS=20.4
Resid=3.6
alpha=3.51
beta=1.75
brxx_ICC_general(WS=WS,Resid=Resid,alpha=alpha,beta=beta,CI=0.95,items=5)
