"WebIt is commonly stated that the degrees of freedom for the chi-square distribution of the statistic are then k − 1 − r, where r is the number of unknown paraméters. This result is valid when the original data was multinomial and hence the estimated paraméters are efficient for minimizing the chi-square statistic. " - Fischer statistic

WebTherefore, the Factorization Theorem tells us that Y = X ¯ is a sufficient statistic for μ. Now, Y = X ¯ 3 is also sufficient for μ, because if we are given the value of X ¯ 3, we can easily get the value of X ¯ through the one-to-one function w = y 1 / 3. That is: W = ( X ¯ 3) 1 / 3 = X ¯. On the other hand, Y = X ¯ 2 is not a ...
