- Random effect of den ID: var = 0.42.  Estimated coefficients of a generalized linear mixed effects model (binomial error distribution) for the probability of an Arctic fox den to be active in a certain year. Fixed effects were the log of the index of small rodent abundance in June and high availability of reindeer carcasses in the previous winter. Den ID was included as random effect on the intercept. Estimates are given on the logit scale with standard error (SE) and 95% bootstrap confidence intervals (CI)
