Conditional Association, Essential Independence and Monotone Unidimensional Item Response Models
Conditional Association, Essential Independence and Monotone Unidimensional Item Response Models
We consider two recent approaches to characterizing the manifest probabilities of a strictly unidimensional latent variable representation (one satisfying local independence and response curve monotonicity with respect to a unidimensional latent variable) for binary response variables, such as those arising from the dichotomous scoring of items on standardized achievement and …
