The Moments of Log-Weibull Order Statistics
TLDR
In this paper, a number of formulae expressing E(i, n) in terms of M(j), j ≤ n, are developed for order statistics of a random sample of size n.Abstract:
Let X 1n ≤ X 2n ≤,…, ≤ Xnn be the order statistics of a random sample of size n. For any integrable function g(x) define E(i, n) = E(g(X in )) and M(n) = E(1, n) = E(g(X 1n )). A number of formulae expressing E(i, n) in terms of M(j), j ≤ n, are developed. For example, These results are applied to obtain the means and variances of the order statistics of a log-Weibull distribution (F(z) = 1 – exp (− exp x)). Tables of these means and variances are given for 1 ≤ i ≤ n, n = 1 (1) 50 (5) 100. The computations were made using a set of 100 decimal place logarithms of integers. Examples of the use of these tables in obtaining weighted least squares estimates from censored samples from a Weibull distribution are also given.read more

TL;DR: In this article, the scale and location parameters of the extreme value distribution were estimated by linear functions of order statistics from Type II progressively censored samples, and four types of linear estimators were considered: the best linear unbiased (BLU), an approximation to the BLU, unweighted regression, and a linearized maximum likelihood.
