Nettet14. nov. 2024 · Integrated step-selection analyses also require several additional steps to translate model parameters into a full-fledged movement model, and the … NettetInstead, iSSA relies on simultaneously estimating movement and resource selection parameters, thus allowing simple likelihood‐based inference of resource selection within a mechanistic movement model. We provide theoretical underpinning of iSSA, as well as practical guidelines to its implementation.
