This dataframe contains the error diagnosis of the analyzed articles that contained an error and has the following components:
Source: Name of the file of which the statistic is extracted
Raw: Raw string of the statistical reference that is extracted
Computed: The recomputed pvalue
OneTail: Logical. Is it likely that the reported p value resulted from a correction for onesided testing?
CorrectRound: Logical. Is the reported p value correct when we take the possibility into account that the test statistic was rounded after calculating the corresponding p value? For instance, a reported t value of 2.35 could correspond to an actual value of 2.345 to 2.354 with a range of p values that can slightly deviate from the recomputed p value but still be correct.
RoundError: Logical. P value wrongly rounded upward or downward. E.g. rounding a p value of .049 to .04.
PSmallerThanZero: Logical. Reported p <.000.
SmallerInsteadEqual: Logical. Reported "<" when "=" would be correct. E.g. F(2,20)=2.33, p <.123, whereas the correct p value is equal to .123.
Bonferroni: Logical. Could the reported p value have resulted from a Bonferroni correction? Note: The corrected p values were calculated by multiplying the reported p values by the number of statistical results reported in one article. This is a rough estimation.
Unidentifiable: Logical. The error could not be classified on the basis of the extracted information.
CopyPaste: Logical. Does the exact string of the extracted raw results occur anywhere else in the article?
This dataframe contains an overview of the detected copypaste errors in all the articles. Its components are the same as the ones in ErrorDiagnosis. Note that a copypaste error could still be congruent in terms of test statistic and p value, so it is possible that these errors do not show up in ErrorDiagnosis.
This dataframe provides a summary of all detected errors. It summarizes the number of detected errors in each of the aforementioned categories per article. The copypaste errors are counted in a way that two identical strings of results are counted as one copypaste error.
a list that contains four dataframes: ErrorDiagnosis, CopyPaste, Summary, and FullDiagnosis. In the following sections the content of these dataframes will be described in detail.
