background: determining the mortality rate of diseases in a community is one of the main components in health care planning of that community. this study used a join point regression model to determine the trend of mortality due to diabetes mellitus (dm) in iran. materials and methods: the data on the rate of mortality due to dm were obtained from the reports of the iranian ministry of health. ...

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...

In this paper, we consider the estimation of the unknown parameter of the scaled logistic distribution on the basis of record values. The maximum likelihood method does not provide an explicit estimator for the scale parameter. In this article, we present a simple method of deriving an explicit estimator by approximating the likelihood function. Bayes estimator is obtained using importance samp...
