Building Hierarchies of Factors with Disjoint Factor Analysis,at there is a hierarchical relationship among these observable variables, a broader underlying concept can be represented as a tree-like structure, where each internal node represents a different level of abstraction for the concept being measured. In this chapter, we introduce a novel method for moBLANK 发表于 2025-3-25 17:35:10
Uncertainty in Latent Trait Models and Dimensionality Reduction Methods for Complex Data: An Analys latent traits. This chapter proposes a hybrid model as an alternative to the conventional analysis that relies on the sum of individual item scores. Our approach involves synthesizing responses from multiple ordinal items into a single score using a dimension reduction approach. This synthesized sc拍下盗公款 发表于 2025-3-25 21:00:00

Stability of Nonparametric Methods for Cognitive Diagnostic Assessment,en discrete, possess scientific interpretations, such as skill mastery in educational assessments, mental disorders in psychiatric diagnoses, or the presence of disease pathogens in biological samples. Nonparametric CDMs directly classify subjects into latent profiles by minimizing the distance betw
