Description: A single-call data quality assessment scoring a data set on the
    five inherent characteristics of the ISO/IEC 25012 data quality model
    (accuracy, completeness, consistency, credibility and currentness) through
    the fifteen quality properties beneath them, ISO/IEC (2008)
    <https://www.iso.org/standard/35736.html>. Each property is measured as a
    ratio of counted data items, the form ISO/IEC 25024 measurement functions
    take, ISO/IEC (2015) <https://www.iso.org/standard/35749.html>. Six
    properties are computable from a table alone; the rest compare the data
    against expectations declared through a specification object, and are
    reported as not applicable rather than approximated when none is supplied.
    Also reports missing-data patterns, duplicates, redundant columns, outliers,
    multicollinearity and distributional deviations, and returns a structured
    object with plots rather than console text alone. The statistics implement
    the methodology of the author's master's dissertation, Demirhan (2024)
    "Assessing Data Quality Management Issues in Open-Sourced Data Sets with
    Statistical Methodology"
