Summed Score Likelihood–Based Indices for Testing Latent Variable Distribution Fit in Item Response Theory
In standard item response theory (IRT) applications, the latent variable is typically assumed to be normally distributed. If the normality assumption is violated, the item parameter estimates can become biased. Summed score likelihood–based statistics may be useful for testing latent variable distri...
