title: 'RobustFlow: Robustness and Drift Auditing for Longitudinal Decision Systems'
version: 0.1.1
doi: 10.32614/CRAN.package.RobustFlow
abstract: 'Provides tools for constructing longitudinal decision paths, quantifying
  temporal drift, tracking subgroup disparity trajectories, and stress-testing longitudinal
  conclusions under hidden bias. Implements three signature metrics: the Drift Intensity
  Index (DII), which measures structural instability in transition dynamics using
  the Frobenius norm of consecutive transition matrix differences; the Bias Amplification
  Index (BAI), which quantifies whether group disparities widen or converge over time;
  and the Temporal Fragility Index (TFI), which estimates the minimum hidden-bias
  perturbation required to nullify a longitudinal trend conclusion. An interactive
  ''shiny'' application supports exploratory analysis, visualization, and reproducible
  reporting. Methods are motivated by applications in educational and social science
  research, including the Early Childhood Longitudinal Study (ECLS). The DII is based
  on the Frobenius norm as described in Golub and Van Loan (2013, ISBN:9781421407944).
  The TFI extends the hidden-bias sensitivity framework of Rosenbaum (2002, ISBN:9781441912633).
  The BAI draws on disparity-trajectory methods discussed in Duncan and Murnane (2011,
  ISBN:9780871542731).'
