In brxx: Bayesian Test Reliability Estimation

Description

This function estimates reliability from given true and error variance estimates.

Usage

brxx_general(a, b, alpha, beta, CI, items)

Arguments

a	True score variance estimate.
b	Error 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

a=18.7
b=3.3
alpha=3.51
beta=1.75
brxx_general(a=a,b=b,alpha=alpha,beta=beta,CI=0.95,items=10)
