Tab. 3. Generalized additive model of the maximum diving depth. Included are the predictor variables sea surface temperature (SST) and movement mode (MovMod), the coefficient estimate (Est.), standard errors (SE), z-statistics (z) of the categorical variable, effective (Edf.) and reference (Ref.df) degrees of freedom, and χ 2 -statistics (Chi.sq) of the continuous variable, and corresponding p -values (p).
