WebMar 7, 2024 · L ( θ) = ( 2 π θ) − n / 2 exp ( n s 2 θ) Where θ is an unknown parameter, n is the sample size, and s is a summary of the data. I now am trying to show that s is a sufficient statistic for θ. In Wikipedia the Fischer-Neyman factorization is described as: f θ ( x) = h ( x) g θ ( T ( x)) My first question is notation.

WebJan 6, 2015 · Fisher-Neyman's factorization theorem. Fisher's factorization theorem or factorization criterion. If the likelihood function of X is L θ (x), then T is sufficient for θ if and only if. functions g and h can be found such that. Lθ ( x) = h(x) gθ ( T ( x)). i.e. the likelihood L can be factored into a product such that one factor, h, does not WebFactorization Theorem : Fisher–Neyman factorization theorem Fisher's factorization theorem or factorization criterion provides a convenient characterization of a sufficient statistic.
