public class Huynh
extends java.lang.Object

Computes Huynh's decision consistency indices. This class is a translation of Huynh's original FORTRAN code.

Author:

J Patrick Meyer A computer program to compute the reliability indices for decision in mastery testing and their standard errors of estimate based on the Beta-Binomial model. Input data are: N=number of items, M=number of examinees, K=number of classification categories XBAR=mean of test scores SD=standard deviation of test scores L=cut scores References: Huynh, H.
