%description
Detects concept drift and data drift in streams produced by deployed
machine learning models, using a tidy interface that composes with the
'tidymodels' ecosystem. Detectors are specified, fitted on a baseline
period, and advanced over new batches of observations, returning tibbles
annotated with warning and drift flags. A catalogue of 22 sequential drift
detectors is provided. Error-based methods include the Drift Detection
Method (DDM) of Gama et al. (2004) <doi:10.1007/978-3-540-28645-5_29>, the
Early Drift Detection Method (EDDM) of Baena-Garcia et al. (2006), the
Hoeffding's inequality based Drift Detection Methods (HDDM) of
Frias-Blanco et al. (2015) <doi:10.1109/TKDE.2014.2345382>, and the
Exponentially Weighted Moving Average (EWMA) chart of Ross et al. (2012)
<doi:10.1016/j.patrec.2011.08.019>. Distribution-based methods include
Adaptive Windowing (ADWIN) of Bifet and Gavalda (2007)
<doi:10.1137/1.9781611972771.42>, Kolmogorov-Smirnov Windowing (KSWIN) of
Raab et al. (2020) <doi:10.1016/j.neucom.2019.11.111>, and the
Page-Hinkley test of Page (1954) <doi:10.1093/biomet/41.1-2.100>.
