The Kullback-Leibler divergence is a common measure of shifted probability distributions, for which discretized versions are invented to deal with binned or categorical data. We present the Unstable Population Indicator, a robust, flexible and numerically stable, discretized implementation of Jeffrey's divergence, along with an implementation in a Python package that can deal with continuous, discrete, ordinal and nominal data in a variety of popular data types. We show the numerical and statistical properties in controlled experiments. It is not advised to employ a common cut-off to distinguish stable from unstable populations, but rather to let that cut-off depend on the use case."; dct:date "2024"; dct:hasPart ; dct:isPartOf ; dct:title "Measuring Data Drift with the Unstable Population Indicator"; pav:authoredBy orcid:0000-0003-2581-8370, orcid:0009-0003-5030-0108; a . orcid:0000-0003-2581-8370 , ; "datascience@marcelhaas.com"; a foaf:Person; foaf:name "Marcel R.
