Figure 2.

Graphical representation of the robit regression for group membership predictors of the HMM with environmental covariate. (a) Carbon and (b) nitrogen isotope values had a significant effect on predicting whether a pup's weaning mass was small (p = 0) or large (p = 1). (c) The effect of weaning date was also suggestive, although not statistically significant at the 95% level. (a–c) Histograms of the raw data are depicted above each plot. (d) Depicts the effect size of the estimated regression coefficients (on the robit scale). Reported estimates are for standardized variables. The grey envelope corresponds to a 95% credibility interval, and the black line to the posterior mean.
