bspam - Speed-Accuracy Psychometric Modeling for Binomial Count Outcome Data

Provides functions to fit speed-accuracy psychometric models for binomial count outcome data. The models jointly represent accuracy and response time and can be used for model-based calibration and scoring of oral reading fluency (ORF) assessment data. The methods are based on Potgieter, Kamata and Kara (2017) <doi:10.48550/arXiv.1705.10446> and Kara, Kamata, Potgieter and Nese (2020) <doi:10.1177/0013164419900208>.
