While my favorite is still the reply by E.S. Pearson, which alone should have shattered Fisher's allegations that N-P …
WebNeyman-Fisher, Theorem Better known as “Neyman-Fisher Factorization Criterion”, it provides a relatively simple procedure either to obtain sufficient statistics or check if a specific statistic could be sufficient. Fisher was the first who established the Factorization Criterion like a sufficient condition for sufficient statistics in 1922 ...

WebMay 15, 2024 · In modern statistical data analysis, often Fisher's P value and the Neyman-Pearson value of α are either confused or mixed. 5 The two approaches were originally quite distinct, but some mixing is inevitable. For example, Fisher advocated against using the Alternative Hypothesis, whereas Neyman and Pearson introduced this.

Fisher's factorization theorem or factorization criterion provides a convenient characterization of a sufficient statistic.
