Statistical analysis
Analysis was conducted in R version 3.6.2 using the Bayesian packagebrms (Bürkner 2017) an interface to Stan (Stan Development Team
2015) for linear mixed-effects models (see Supplement). FIDs were
square-root transformed prior to analysis to meet model assumptions of
normality of residuals. We report posterior means for all estimated
parameter with 95% credibility intervals (CIs).
