ss3diags - Advanced diagnostics to evaluate a Stock Synthesis model

The R package ss3diags enables users to apply advanced diagnostics to evaluate a Stock Synthesis model. Key functions include running and visualizations of diagnostic tests such as residual analyses, hindcasting cross-validation techniques, and retrospective analyses, as presented in the paper A Cookbook for Using Model Diagnostics in Integrated Stock Assessments. The package works closely with r4ss to make a seamless workflow for the users to evaluate the statistical robustness of their stock assessment model.
