A Generalized Linear Model (GLM) with two predictors and a logistic link function was used to predict SWR reactivation based on firing similarity and firing measures. Firing similarity measures (X1) but no other firing measures (X2) significantly predicted SWR reactivation as indicated by the significance of the β values. SWR reactivation was modeled as a binomial distribution (0 for non-reactivated and 1 for reactivated). β values are expressed as standard errors to allow comparison between predictors. Firing rate measures are mean and peak rates of mean trial firing across all trajectories. Trial coverage is defined as the number of consecutive trial phase bins around the peak trial phase with firing rate exceeding 2/3 of maximum rate. Trial coverage was calculated for the mean trial firing rate for trials on the most active firing trajectory or for all trajectories. Speed-firing rate correlation is the correlation for speed and firing rate residuals for each trial phase for trials on the same trajectory
