title: 'DecisionDrift: Detecting, Decomposing, and Stress-Testing Temporal Change
  in Repeated Decision Systems'
version: 0.1.0
doi: 10.32614/CRAN.package.DecisionDrift
abstract: 'Tools for detecting, decomposing, and stress-testing temporal drift in
  repeated binary decision systems. Complements the ''decisionpaths'' package by shifting
  focus from path construction to system-level change over time. Implements five core
  analytic modules: (1) prevalence drift — did the overall decision rate change over
  time?; (2) transition drift — did the probability of switching or persisting change?;
  (3) entropy and stability trends — did path complexity evolve?; (4) group-differential
  drift — did the system drift differently across subgroups?; (5) change-point and
  regime-shift detection — did the system change abruptly after a policy or model
  update? Additionally provides a robustness module for testing stability of drift
  conclusions across analytic choices, and a sensitivity module for probing vulnerability
  to data problems including missingness, miscoding, and threshold shifts. Defines
  four original drift indices: the Decision Drift Index (DDI), Transition Drift Index
  (TDI), Group Differential Drift (GDD), and Cumulative Drift Burden (CDB). Applications
  include algorithmic audit, AI governance, education, health, and organisational
  research.'
