Abstract
This repository contains data and R code (along with associated output from running the code) supporting all results reported in: Chatterjee, Nilanjan; Wolfson, David; Kim, Dongmin; Vélez, Juliana; Freeman, Smith; Bacheler, Nathan; Shertzer, Kyle; Taylor, J.; Fieberg, John 2024. Modelling individual variability in habitat selection and movement using integrated step-selection analysis. Methods in Ecology and Evolution. The code demonstrates how to model the individual variation in habitat selection and movement parameters using integrated step-selection analysis.
Description
See the uploaded readme file.
Update 2025-04-25: Since initial publication, the mixedSSA R package referenced in this DRUM repository has been updated, and we have identified a mistake in one of the equations in the appendix. We have contacted the journal and submitted an erratum, and they have also requested that we update the associated supporting documents. Three files have been added to address this update (Update_delta_method.html, Update_delta_method.R, and helper_functions.R).
