WebMar 21, 2024 · Fisher’s p-value is incompatible with the Neyman-Pearson hypothesis test. Marrying two approaches can lead to internal inconsistencies. Fisher’s p-value is an indirect measure of evidence, using data from a single study. The Neyman-Pearson framework is about setting long-run frequencies of errors, over many studies. WebP-values are to be used flexibly in this framework, with the P-value interpreted as "a rational and well-defined measure of reluctance to accept the hypotheses they test" (Fisher, 1973, page 47). Although many have mistakely suggested a single threshold for determining "statistical significance" (myself included, mea culpa!), Fisher noted "no ... soft toy orangutan
