as is well known, estimating parameters of the tree-parameter weibull distribution is a complicated task and sometimes contentious area with several methods vying for recognition. weibull distribution involves in reliability studies frequently and has many applications in engineering. however estimating the parameters of weibull distribution is crucial in classical ways. this distribution has t...

The Weibull distribution has been widely used in survival and engineering reliability analysis. In life testing experiments is fairly common practice to terminate the experiment before all the items have failed, that means the data are censored. Thus, the main objective of this paper is to estimate the reliability function of the Weibull distribution with uncensored and censored data by using B...

The Weibull distribution is a very applicable model for the lifetime data. For inference about two Weibull distributions using records, the shape parameters of the distributions are usually considered equal. However, there is not an appropriate method for comparing the shape parameters in the literature. Therefore, comparing the shape parameters of two Weibull distributions is very important. I...

We propose the Weibull negative binomial distribution that is a quite flexible model to analyze positive data, and includes as special submodels the Weibull, Weibull Poisson and Weibull geometric distributions. Some of its structural properties follow from the fact that its density function can be expressed as a mixture of Weibull densities. We provide explicit expressions for moments, generati...

We develop a version of the Corrected Akaike Information Criterion (AICC) suitable for selection of an h-step-ahead linear predictor for a weakly stationary time series in discrete time. A motivation for this criterion is provided in terms of a generalized Kullback-Leibler information which is minimized at the optimal h-step predictor, and which is equivalent to the ordinary Kullback-Leibler in...

In this paper, we derived recurrence relations for joint moment generating functions of nonadjacent generalized order statistics (GOS) of random samples drawn from doubly truncated class of continuous distributions. Recurrence relations for joint moments of nonadjacent GOS (ordinary order statistics (OOS) and k-upper records (k-RVs) as special cases) are obtained. Single and product moment gene...

A novel model selection and averaging approach is proposed—through integrating the corrected Akaike information criterion (AICc), Gibbs sampler, Poisson regression models, to improve tropical cyclone seasonal forecasting in Australian South Pacific Ocean regions sub-regions. It has been found by new that indices which describe inter-annual variability such as Dipole Mode Index (DMI) El Niño Mod...

This article considers the analysis of experiment of repeated measures design that is used frequently in medical research. We propose new approach could be used to guide the selection of the covariance structure. We used simulation study to compare six model selection criteria in terms of their ability to identify the right correlated error model with the help of the new approach. The compariso...

The enhanced heat resistance of Salmonella developed at low water activity makes it a serious challenge to eliminate them during thermal processing. objectives this research are (i) investigate the effect on inactivation cocktail (Agona, Tennessee, Mbandaka, Montevideo, and Reading) in dried basil leaves, (ii) evaluate Enterococcus faecium NRRL B-2354 as an appropriate surrogate for leaves.
