Existing fairness metrics treat bias as a\nsingle-period snapshot; this package operationalizes the view\nthat bias in sequential systems must be measured over time.\nImplements group-specific decision-rate trajectories,\nstandardized disparity measures analogous to the standardized\nmean difference (Cohen, 1988, ISBN:0-8058-0283-5), cumulative\nbias burden, Markov-based transition disparity (recovery and\nretention gaps), and a dynamic amplification index that\nquantifies whether prior decisions compound current group\ninequality. The amplification framework extends longitudinal\ncausal inference ideas from Robins (1986)\n and the sequential\ndecision-process perspective in the fairness literature (see\n) to the audit setting.\nCovariate-adjusted trajectories are estimated via logistic\nregression, generalized additive models (Wood, 2017,\n), or generalized linear mixed\nmodels (Bates, 2015, ). Uncertainty\nquantification uses the cluster bootstrap (Cameron, 2008,\n).", "License": "MIT + file LICENSE", "Encoding": "UTF-8", "Language": "en-US", "Roxygen": "list(markdown = TRUE)",
