Extended Data Fig. 5: Mixture modeling of behavior.
From: Intermittent rate coding and cue-specific ensembles support working memory
(A) Histogram of confidence values during memory delay time points (one cue location) from three example sessions. Dashed line shows the best fitting beta distribution. Solid line shows the best fitting mixture of two beta distributions. Purple and yellow lines show the individual component distributions for the two-state model. (B) Histogram showing average proportion-weighted component modes (bootstrap). (C) Cross-validated model comparison results for 2-state vs 1-state fits for all sessions (N = 25). The 2-state model outperforms the 1-state (p = 0.009, chi-squared). Light circles show individual session scores; dark circle shows mean across sessions; black line shows equivalent model performance.
