Adaptive Numerical Integration for Item Response Theory. Research Report. ETS RR-07-06
Antal, Tamás; Oranje, Andreas
ETS Research Report Series, Mar 2007
Well-known numerical integration methods are applied to item response theory (IRT) with special emphasis on the estimation of the latent regression model of NAEP [National Assessment of Educational Progress]. An argument is made that the Gauss-Hermite rule enhanced with Cholesky decomposition and normal approximation of the response likelihood is a fast, precise, and reliable alternative for the numerical integration in NAEP and in IRT in general.
