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 ... citibank customer chat india

WebJSTOR Home Roughly, given a set of independent identically distributed data conditioned on an unknown parameter , a sufficient statistic is a function whose value contains all the information needed to compute any estimate of the parameter (e.g. a maximum likelihood estimate). Due to the factorization theorem (see below), for a sufficient statistic , the probability density can be written as . From this factorization, it can easily be seen that the maximum likelihood estimate of will intera…
