Effects of \(\text {E}(R)\) and \(\text {Var}(R)\) on on the mean (A–C) and variance (D–F) in simulated home-range size with 95% Bayesian credible intervals. While the estimated marginal effect of \(\text {Var}(R)\) on \(\text {E}(H)\) is sublinear (B), the effect of \(\text {Var}(R)\) is superlinear for high values of \(\text {E}(R)\) (C). The relationships were estimated using a Generalized Additive Model for Location and Scale with a Gamma location-scale family of distributions (\(\mathtt {mgcv\!::\!gammals}\)). Credible intervals were calculated using 10,000 samples from the posterior distribution while assuming multivariate Gaussian coefficients. Additional details on the model structure are provided in Appendix B
