Quantile binning and overnight shifts of simulated data.

Fixed effects parameter estimates (+/- standard errors) for comparisons of quantile-dependent overnight shifts in performance in simulations with free or fixed within-day entropy. The quantile-dependence of overnight shifts is significant in free-entropy simulations and eliminated by a significant interaction with entropy condition in fixed-entropy simulations, regardless of the quantile binning strategy. We included random effects of bird (n = 5) and syllable (n = 13) for all parameters. (XLSX)
