On the Latent Regression Model of Item Response Theory. Research Report. ETS RR-07-12
Antal, Tamás
ETS Research Report Series, Mar 2007
Full account of the latent regression model for the National Assessment of Educational Progress is given. The treatment includes derivation of the EM algorithm, Newton-Raphson method, and the asymptotic standard errors. The paper also features the use of the adaptive Gauss-Hermite numerical integration method as a basic tool to evaluate expectations necessary to perform the parameter estimations.
