Web5.7.3 Validation. False discovery rates (false positives) are a major problem in proteomics and can be caused by: (1) the statistical process used to identify significant protein signal differences, and (2) the algorithms used for identifying the structures of such proteins.

Note that in the Fisher's approach to statistical testing, p-value is taken as the strength of the evidence against the null; it is only the Neyman-Pearson approach that demands to choose an alpha beforehand and not pay attention to the p-value apart from checking if it below alpha or not. Benjamini (2010) said that the false discovery rate, and the paper Benjamini and Hochberg (1995), had its origins in two papers concerned with multiple testing: ...
