Table 3 Odds ratio estimates (OR) and 90% confidence intervals (90% CI) for the top supported model of three-dimensional overlap of utilization distributions, estimated as the volume of intersection, for wild pigs (Sus scrofa) across time periods (Season-long [nseason = 2; npigs = 14], Month [nmonths = 6; npigs = 18], and Week [nweeks = 26; npigs = 17]) tracked on Savannah River Site, South Carolina, USA during 2014 and 2016. Colons separating predictor names denote interaction terms and asterisks denote 90% CI of odds ratios that did not overlap 1.
