Applied
IRT-Software
IRT-Software uses several techniques to
estimate person and item parameters (e.g. MLE, WLE, BME by Hoijtink
& Boomsma, 1995; MLE, WLE, BME, EAP by Kim & Nicewander, 1993; WLE, MLE, BME, OSB and naming also
h-estimators, biweight and jackknifed
estimators by Warm, 1989; EM, MLF, CMLF by Rigdon
& Tsatakawa, 1983).
Basically
plenty of IRT-Software is available (A Fortran Program by Fischer & Scheiblechner, 1970; LOGISTIC by Wood, Wingersky
& Lord, 1976; BMD by Dixon & Brown, 1977; ECTA by Goodman & Fay,
1974; BICAL by Wright & Mead, 1977; DICOT by Masters, 1984; LATENT GOLD,
2000; ICL by Hanson, 2002).
To estimate the Rasch variances of person parameters the applied IRT-Software
is of interest, so we also evaluate different software in our project.
