A Continuous-Time Dynamic Choice Measurement Model for Problem-Solving Process Data
Yunxiao Chen
Problem solving has been recognized as a central skill that today's students need to thrive and shape their world. As a result, the measurement of problem-solving competency has re…
Detection of Two-Way Outliers in Multivariate Data and Application to Cheating Detection in Educational Tests
Yunxiao Chen, Yan Lu, Irini Moustaki
The paper proposes a new latent variable model for the simultaneous (two-way) detection of outlying individuals and items for item-response-type data. The proposed model is a syner…
A Note on Exploratory Item Factor Analysis by Singular Value Decomposition
Haoran Zhang, Yunxiao Chen, Xiaoou Li
We revisit a singular value decomposition (SVD) algorithm given in Chen et al. (2019b) for exploratory Item Factor Analysis (IFA). This algorithm estimates a multidimensional IFA m…
A Latent Gaussian Process Model for Analyzing Intensive Longitudinal Data
Yunxiao Chen, Siliang Zhang
Intensive longitudinal studies are becoming progressively more prevalent across many social science areas, especially in psychology. New technologies like smart-phones, fitness tra…
