Table 2 Zero inflated negative binomial model outputs for capture rates of (a) wolverine, (b) American marten and (c) short-tailed weasel. Table values include regression coefficients estimate (\(\beta\)), exponentiated regression coefficients (exp(\(\beta\))) that represent the odds ratio, standard deviation (SD) and p-value (significance level = 0.05, indicated with ‘*’).
