WebJul 25, 2011 · Classical statistical theory—hypothesis testing, estimation, and the design of experiments and sample surveys—is mainly the creation of two men: Ronald A. Fisher (1890-1962) and Jerzy Neyman (1894-1981). Their contributions sometimes complemented each other, sometimes occurred in parallel, and, particularly at later stages, often were in ... Websay, a factorisation of Fisher-Neyman type, so Uis su cient. // So if, e.g. T is su cient for the population variance ˙2, p T is su cient for the standard deviation ˙, etc. Note. From SP, you know Measure Theory, so the above proof may strike you as crude. It is. For the full story, see e.g. P. R. HALMOS and L. J. SAVAGE, Application of the ... Fisher's factorization theorem or factorization criterion provides a convenient characterization of a sufficient statistic. If the probability density function is ƒθ(x), then T is sufficient for θ if and only if nonnegative functions g and h can be found such that $${\displaystyle f_{\theta }(x)=h(x)\,g_{\theta }(T(x)),}$$ … See more In statistics, a statistic is sufficient with respect to a statistical model and its associated unknown parameter if "no other statistic that can be calculated from the same sample provides any additional information as to … See more A sufficient statistic is minimal sufficient if it can be represented as a function of any other sufficient statistic.
