Appendix 5—table 1. Bayesian regression model results of the main dataset.
Adjusted specParam fitting parameters (peak width limits: [1 8]; max number of peaks: 6; minimum peak height: 0.1; peak threshold: 2 sd above mean; aperiodic mode: fixed) and data exclusion criteria of specParam fit: MAE >0.1 or MAE <0.025.
