Statcheck information

Statcheck is an R package designed to detect statistical errors in peer-reviewed psychology articles^[1] by searching papers for statistical results, redoing the calculations described in each paper, and comparing the two values to see if they match.^[2] It takes advantage of the fact that psychological research papers tend to report their results in accordance with the guidelines published by the American Psychological Association (APA).^[3] This leads to several disadvantages: it can only detect results reported completely and in exact accordance with the APA's guidelines,^[4] and it cannot detect statistics that are only included in tables in the paper.^[5] Another limitation is that Statcheck cannot deal with statistical corrections to test statistics, like Greenhouse–Geisser or Bonferroni corrections, which actually make tests more conservative.^[6] Some journals have begun piloting Statcheck as part of their peer review process. Statcheck is free software published under the GNU GPL v3.^[7]
