Exploratory Hierarchical Factor Analysis with an Application to Psychological Measurement
Jiawei Qiao, Yunxiao Chen, Zhiliang Ying
Hierarchical factor models, which include the bifactor model as a special case, are useful in social and behavioural sciences for measuring hierarchically structured constructs. Sp…
A Dynamic Factor Model for Multivariate Counting Process Data
Fangyi Chen, Hok Kan Ling, Zhiliang Ying
We propose a dynamic multiplicative factor model for process data, which arise from complex problem-solving items, an emerging testing mode in large-scale educational assessment. T…
Exact Exploratory Bi-factor Analysis: A Constraint-based Optimisation Approach
Jiawei Qiao, Yunxiao Chen, Zhiliang Ying
Bi-factor analysis is a form of confirmatory factor analysis widely used in psychological and educational measurement. The use of a bi-factor model requires the specification of an…
