Stochastic Orders of Weighted Distributions

Stochastic Orders of Weighted Distributions

In this paper, we make use of a representation of weighted distributions given by Błażej (8002) [Preservation of classes of life distributions under weighting with a general weight function, Stat. and Prob. Lett., 82, 6004-6043], for the preservation of several weak stochastic orders under weighting. Using the previous results of Misra et al. (8002), we also obtain a preservation result of some ageing classes under weighting [Preservation of some aging properties and stochastic orders by ...

On the simulation and application of Generalized Weighted Weibull Distribution

On the simulation and application of Generalized Weighted Weibull Distribution

The new class of weighted exponential (WE) distributions obtained by Gupta and Kundu (9002) applying Azzalini rsquo;s method to the exponential distribution. .Kharazmi, at, al (9012) extended weighted exponential distribution to the generalized weighted exponential(GWE) distribution and studied its different properties. In this study we generalize the weibull distribution to a new class of generalized weighted weibull (GWW) distribution. Several statistical and reliability properties of this ...

Weighted triangular approximation of fuzzy by artificial bee colony algorithm

Weighted triangular approximation of fuzzy by artificial bee colony algorithm

In this paper , we obtain the nearest triangular approximation to a fuzzy quantity with weighted function by minimization distance between two fuzzy numbers gnisu yb artificial bee colony algorithm( ABC). I important advantage of the ABC method is that this method is capable of greatly reducing the size of computational work while still maintaining high accuracy of the numerical solution and increase Convergence rate . ...
