Changes in version 0.1.1 (2026-04-06) - Updated amplification index to a mechanism-oriented sign convention: A_t = (p11_ref - p11_group) - (p01_ref - p01_group). Negative values indicate recovery-driven amplification against the focal group; positive values indicate retention-driven amplification. - Added sign argument to aib_amplify() with options "mechanism" (default) and "legacy" for backward compatibility. - Improved documentation to clarify sign interpretation. - Fixed: \dontrun{} replaced with \donttest{} in examples. - Fixed: added \value tags to print.aibias and summary.aibias. - Fixed: aib_figures() default path now uses tempdir(). Changes in version 0.1.0 (2026-04-04) - Initial CRAN submission. - Core functions: aib_build(), aib_describe(), aib_transition(), aib_amplify(), aib_adjust(), aib_bootstrap(), aib_audit(). - Four plot types via plot.aibias(): trajectory, heatmap, transition, amplification. - Includes lending_panel synthetic dataset (600 applicants x 6 years, 3 racial groups). - Demo script reproducing all four paper figures: demo("paper_figures", package = "AIBias"). Resubmission notes - Removed author surnames from DESCRIPTION to avoid spell check false positives (Barocas, Hardt, Narayanan, Gelbach replaced with neutral citation wording). - Added .gitignore to exclude cran-comments.md from the repository.
