The general approach and background is outlined in the ICCM abstract. The numerical subject-level predictions are in the Excel file `Predicted CPR performance for each subject.xlsx`. There are two different predictions: One with the model calibrated just to the participants' data (non-informative priors), and one with parameter priors based on another study. In this other study, nursing students' CPR performance is tested at different time intervals (i.e., with different retention interval schedules) and the data from this much larger sample (specifically, data from 199 participants that have completed at least 5 sessions) was used to gather *informative* priors for the predictions of the much smaller sample in the current study.
