This repository contains the annual Namibian hake stock assessment, its data and control files, model diagnostics, and the code needed to reproduce the results.

The 2025-to-2026 input-difference
report
identifies every intended input change. Model diagnostics and key results are
available in the reports
directory.
From the repository root, run the four numbered workflow scripts in order:
Rscript scripts/01_validate_inputs.R
Rscript scripts/02_run_assessment.R
Rscript scripts/03_check_models.R
Rscript scripts/04_render_report.R
These stages validate and compare the annual inputs, compile and run the ADMB models, classify convergence, write compact CSV summaries, and render the HTML and PDF reports. The main machine-readable outputs are:
reports/input_changes_2025_to_2026.htmlreports/model_diagnostics_2026.csvreports/key_results_2026.csvvignettes/02-Namibian_hake_model_2026.htmlvignettes/02-Namibian_hake_model_2026.pdfThe dome-shaped selectivity and steepness 0.5 sensitivities currently fail the declared diagnostic criteria. Their estimates are retained for troubleshooting but excluded from inference.
For the exact 2025 reference state, use the immutable
baseline-2025
tag.
