Regularizing threshold priors with sparse response patterns in Bayesian factor analysis with categorical indicators
类别指标贝叶斯因子分析中稀疏响应模式的阈值先验正则化
Using instruments comprising ordered responses to items are ubiquitous for studying many constructs of interest. However, using such an item response format may lead to items with response categories infrequently endorsed or unendorsed completely. In maximum likelihood estimation, this results in non-existing estimates for thresholds. This work focuses on a Bayesian estimation approach to counter this issue. The issue changes from the existence of an estimate to how to…
