Complements\nthe 'decisionpaths' package by shifting focus from path\nconstruction to system-level change over time. Implements five\ncore analytic modules: (1) prevalence drift — did the overall\ndecision rate change over time?; (2) transition drift — did the\nprobability of switching or persisting change?; (3) entropy and\nstability trends — did path complexity evolve?; (4)\ngroup-differential drift — did the system drift differently\nacross subgroups?; (5) change-point and regime-shift detection\n— did the system change abruptly after a policy or model\nupdate? Additionally provides a robustness module for testing\nstability of drift conclusions across analytic choices, and a\nsensitivity module for probing vulnerability to data problems\nincluding missingness, miscoding, and threshold shifts. Defines\nfour original drift indices: the Decision Drift Index (DDI),\nTransition Drift Index (TDI), Group Differential Drift (GDD),\nand Cumulative Drift Burden (CDB). Applications include\nalgorithmic audit, AI governance, education, health, and\norganisational research.", "License": "MIT + file LICENSE", "Encoding": "UTF-8", "Language": "en-GB", "RoxygenNote":
