Fabrication in a study about honesty: A lost episode of columbo illustrating how forensic statistics is performed
1Department of Biostatistics and Bioinformatics, Duke University School of Medicine, Durham, NC, USA.
Abstract:
The three steps of a typical forensic statistical analysis are (1) verify that the raw data file is correct; (2) verify that the statistical analysis file derived from the raw data file is correct; and (3) verify that the statistical analyses are appropriate. We illustrate applying these three steps to a manuscript which was subsequently retracted, focusing on step 1. In the absence of an external source for comparison, criteria for assessing the raw data file were internal consistency and plausibility. A forensic statistical analysis isn't like a murder mystery, and it many circumstances discovery of a mechanism for falsification or fabrication might not be realistic.
