Hi Trevor:

The R package sort (for supplemental item response models) includes a function for calculating Yen’s Q3 and presents an example using the Rasch model:

Hope this helps,
MJY

Dear Colleagues,
It has been claimed that Yen?s Q3 index (1984) can be used to identify local dependence in Rasch analyses.

e.g., Chou, Y.-T., & Wang, W.-C. (2010). Checking dimensionality in item response models with principal component analysis on standardized residuals. Educational and Psychological Measurement, 70(5), 717-731.

Christensen, K. B., Makransky, G., & Horton, M. (2017). Critical values for Yen?s Q3: Identification of local dependence in the Rasch model using residual correlations. Applied Psychological Measurement, 41(3), 178-194.

Have you used Q3 for that purpose? Do you know of papers that have adopted it? Is it helpful/effective? Is it available in the software that you use, or know about?

Looking forward to your advice and guidance.

Collegially

Trevor
