A Solution of the Conditional Estimation Problem for Long Tests in the Rasch Model For Dichotomous Items.

Gustafsson, Jan-Eric

Educational and Psychological Measurement, v40 n2 p377-85 Sum 1980

The statistically correct conditional maximum likelihood (CML) estimation method has not been used because of numerical problems. A solution is presented which allows a rapid computation of the CML esitmates also for long tests. CML has decisive advantages in the construction of statistical tests of goodness of fit.
