1. Concomitants of Dual Generalized Order Statistics from Morgenstern Type Bivariate Generalized Exponential Distribution

Saeid Tahmasebi, Ali Akbar Jafari, Mahmoud Afshari
Pages: 1 - 12
[9] introduced the concept of dual generalized order statistics (dgos) that enables a common approach to descending ordered random variables like reversed order statistics and lower record values. In this paper, we have obtained probability density function (pdf) of r-th, and the joint pdf of r-th and...

2. Assessment of Cpm in the presence of measurement errors

Amit K. Baral, M.Z. Anis
Pages: 13 - 27
With the advent of Taguchi’s loss function, the concept of target and sticking to the target to achieve better process performance has become widely accepted. In practice, while estimating process performance, the gauge measurement error is not taken into consideration. In the real world scenario this...

3. A generalization of Tukey’s g-h family of distributions

J.A. Jiménez, V. Arunachalam, G.M. Serna
Pages: 28 - 44
A new class of distribution function based on the symmetric densities is introduced, these transformations also produce nonnormal distributions and its pdf and cd f can be expressed in parametric form. This class of distributions depend on the two parameters, namely g and h which controls the skewness...

4. Generalized Estimator of Finite population Variance

A.K.P.C. Swain
Pages: 45 - 51
In this paper a generalized class of finite population variance is suggested and its large sample bias and mean square error are derived. Further some special cases of this class are considered along with a numerical example to compute and compare their biases and mean square errors.

5. Edgeworth Expansion of the Parametric Bootstrap t-statistic for Linear Regression Processes with Strongly Dependent Errors

Mosisa Aga
Pages: 52 - 59
The purpose of this paper is to provide a valid Edgeworth expansion for the parametric bootstrap t-statistic of a linear regression process whose error terms are stationary, Gaussian, and strongly dependent time series. Under some sets of conditions on the spectral density function and the parametric...

6. The beta exponentiated Lindley distribution

J.A. Rodrigues, A.P.C.M. Silva, G.G. Hamedani
Pages: 60 - 75
In this work, we study the beta exponentiated Lindley distribution which includes as special cases several models such as the Lindley, exponentiated Lindley and beta Lindley distributions. Some structural properties of the proposed distribution are studied including expressions for the moments. The estimation...

7. Stochastic Properties of the Weighted Hazard Rate Order

S. Izadkhah, M. Amini, G.R. Mohtashami Borzadaran
Pages: 76 - 88
The hazard rate order between two weighted distributions with a given weight function is considered as a new stochastic order called weighted hazard rate order. The influences of biased sampling methods on properties of the hazard rate order are usefully pointed out with this weighted order. We first...

8. On the Properties of Estimates of Monotonic Mean Vectors for Multivariate Normal Distributions

Abouzar Bazyari
Pages: 89 - 106
.Problems concerning estimation of parameters and determination the statistic, when it is known a priori that some of these parameters are subject to certain order restrictions, are of considerable interest. In the present paper, we consider the estimators of the monotonic mean vectors for two dimensional...
