Neyman-Fisher factorization theorem - GM-RKB - Gabor Melli
WebThe support of the distribution depends on the parameter $\theta$.So use indicator functions for writing down the pdf correctly and hence get a sufficient statistic for $\theta$ using Factorization theorem.. First note that WebLet X1, X3 be a random sample from this distribution, and define Y :=u(X, X,) := x; + x3. (a) (2 points) Use the Fisher-Neyman Factorization Theorem to prove that the above Y is a sufficient statistic for 8. Notice: this says to use the Factorization Theorem, not to directly use the definition. Start by writing down the likelihood function. canadian human rights tribunal careers

In my problem I believe what wikipedia represents as x, is θ, and what wikipedia represents as θ is s. Please confirm that that sounds right, it's a point of confusion for me. fisheries ireland
