Abstract
We examine in this paper the implementation of Bayesian point predictors of order statistics from a future sample based on the k th lower record values from a generalized exponential distribution.
Highlights
Let { Xn, n ≥ 1} be a sequence of independent and identically distributed random variables with a cumulative distribution function F ( x; θ ) and a probability density function f ( x; θ ), where θ ∈ Θ could be a real-valued vector
The motivation behind this research follows from the point predictors of order statistics of a future sample from an exponential distribution based on the upper kth record values published in
We addressed the problem of presenting Bayesian point predictors of order statistics of a future sample of size m based on the kth lower record values from a generalized exponential distribution (GED)
Summary
Let { Xn , n ≥ 1} be a sequence of independent and identically distributed (iid) random variables with a cumulative distribution function (cdf) F ( x; θ ) and a probability density function (pdf) f ( x; θ ), where θ ∈ Θ could be a real-valued vector. The definition of the kth record values is as follows: For a fixed k, we define the sequence { Tn,k , n ≥ 1}, of the kth lower record times of { Xn , n ≥ 1} as follows: T1,k = 1, Tn+1,k = min{ j > Tn,k : Xk:Tn,k +k−1 > Xk:j+k−1 }, n ≥ 1, where X j:n denotes the jth order statistic of the sample The problem of predicting record values and order statistics from two independent sequences following two parameter exponential distributions was extensively discussed in [8]. The motivation behind this research follows from the point predictors of order statistics of a future sample from an exponential distribution based on the upper kth record values published in [9]. We deal with point predictors of order statistics based on the lower kth record values from the generalized exponential distribution.
