Least Squares Estimation of Item Response Theory Linking Coefficients.
Ogasawara, Haruhiko
Applied Psychological Measurement, v25 n4 p373-83 Dec 2001
Discusses three types of least squares estimation (generalized, unweighted, and weighted). Results from a Monte Carlo simulation show that, in comparison with other least squares methods, the weighted least squared method generally reduced bias without increasing asymptotic standard errors. (SLD)
