16 p, 179.8 KB Inference on the parameters of the Weibull distribution using records / Jafari, Ali Akbar (Yazd University (Yazd, Iran). Department of Statistics) ; Zakerzadeh, Hojatollah (Yazd University (Yazd, Iran). Department of Statistics)
The Weibull distribution is a very applicable model for lifetime data. In this paper, we have investigated inference on the parameters of Weibull distribution based on record values. We first propose a simple and exact test and a confidence interval for the shape parameter. [...]

20 p, 200.6 KB Exact prediction intervals for future current records and record range from any continuous distribution / Barakat, H. M. (Zagazig University (Zagazig, Egipte). Department of Mathematics) ; Nigm, E. M. (Zagazig University (Zagazig, Egipte). Department of Mathematics) ; Aldallal, R. A. (MSA University (El Caire, Egipte). Department of Mathematics and Statistics)
In this paper, a general method for predicting future lower and upper current records and record range from any arbitrary continuous distribution is proposed. Two pivotal statistics with the same explicit distribution for lower and upper current records are developed to construct prediction intervals for future current records. [...]

24 p, 1.4 MB A comparison of some confidence intervals for estimating the population coefficient of variation: a simulation study / Gulhar, Monika ; Golam Kibria, B. M. ; Albatineh, Ahmed N. ; Ahmed, Nasar U.
This paper considers several confidence intervals for estimating the population coefficient of variation based on parametric, nonparametric and modified methods. A simulation study has been conducted to compare the performance of the existing and newly proposed interval estimators. [...]

20 p, 181.3 KB A simulation study on some confidence intervals for the population standard deviation / Abu-Shawiesh, Moustafa Omar Ahmed ; Banik, Shipra ; Golam Kibria, B. M.
In this paper a robust estimator against outliers along with some other existing interval estimators are considered for estimating the population standard deviation. An extensive simulation study has been conducted to compare and evaluate the performance of the interval estimators. [...]

8 p, 444.3 KB A note on interval estimation for the mean of inverse Gaussian distribution / Arefi, M. (Isfahan University of Technology) ; Mohtashami Borzadaran, G. R. (Ferdowsi University of Mashhad) ; Vaghei, Y. (University of Birjand)
In this paper, we study the interval estimation for the mean from inverse Gaussian distribution. This distribution is a member of the natural exponential families with cubic variance function. Also, we simulate the coverage probabilities for the confidence intervals considered. [...]
