Description: A "spellchecker" for statistics. It checks whether your
        p-values match their accompanying test statistic and degrees of
        freedom. statcheck searches for null-hypothesis significance
        tests (NHST) in APA style (e.g., t(28) = 2.2, p < .05), using
        pattern-matching ("regular expressions"). It recalculates the
        p-value using the reported test statistic and degrees of
        freedom. If the reported and computed p-values don't match,
        'statcheck' will flag the result as an error. If the reported
        p-value is statistically significant and the computed one is
        not, or vice versa, the result will be flagged as a decision
        error. You can use 'statcheck' directly on a string of text,
        but you can also scan a PDF or HTML file, or even a folder of
        PDF and/or HTML files. PDF files are converted to text using
        the R package 'pdftools', so no additional software
        installation is necessary. You can find more information on
        what 'statcheck' can and cannot do and a point-and-click web
        interface to scan PDF or HTML or DOCX articles on
        <https://statcheck.io>.
