Let X1,..., Xn be a random sample from an absolutely continuous (with respect to Lebesgue measure) distribution with the corresponding generalized order statistics X(1, n, m~, k),..., X(n, n, m~,...

Moments of the mth upper record value XU(m), m≥1, and the joint moments of the mth and nth upper record values XU(m) and XU(n), n>m≥1,...

In this paper, we introduce a new class of lifetime distributions which is called the additive Weibull geometric
(AWG) distribution. This distribution obtained by compounding the additive Weibull and geometric distributions.
The new distribution has a number of well-known lifetime special sub-models...

In this paper we modify nonparametric regression-based mean estimators in ranked set sampling using a covariate.
We will show that our modified mean estimators perform well in comparison with their leading competitors.

In this paper, we extend our investigations of a special class of perturbations of copulas introduced in .
Despite a surprising fact that this kind of perturbations does not change the value of tail dependence of the
original copulas, their use yielded models with considerably improved fitting qualities.

Based on the goodness of fit approach, a new test is presented for testing exponentiality against "exponential
Better than Used in moment generating function ordering class" (EBUmgf). The critical values and the powers of
this test are calculated. It is shown that the proposed test...

In this paper, the researchers attempt to introduce a new generalization of the exponential distribution. This
new model is obtained by compounding the exponential distribution and discrete generalized exponential distribution
of a second type, which is a generalization of the geometric distribution....

Statistical analysis of lifetime distributions under Type-II censoring scheme is based on precise lifetime data.
However, in real situations all observations and measurements of Type-II censoring scheme are not precise
numbers but more or less non-precise, also called fuzzy. This paper deals with the...

We show that the Fisher information matrix of the Birnbaum–Saunders distribution can present numerical
problems for some values of the shape parameter. To overcome this problem, we provide a simple analytical
approximation which works very well.
