This book describes EnvStats, a new comprehensive R package for environmental statistics
and the successor to the S-PLUS module EnvironmentalStats for S-PLUS (first released in …

Strategic plans for waste management require information on the current and future waste
generation as a primary data source. Over the years, various approaches and methods for …

The gamma distribution is relevant to numerous areas of application in the physical,
environmental, and biological sciences. The focus of this paper is on testing the shape …

The tolerance package for R provides a set of functions for estimating and plotting tolerance
limits. This package provides a wide-range of functions for estimating discrete and …

We examine the use of fixed-effects and random-effects moment-based meta-analytic
methods for analysis of binary adverse-event data. Special attention is paid to the case of …

It is well-known that maximum likelihood (ML) estimators of the two parameters in a gamma
distribution do not have closed forms. This poses difficulties in some applications such as …

This paper considers interval estimation of stress–strength reliability of k-out-of-n system
when the stress and strength components follow inverse Weibull distributions. Besides the …

The problem of interval estimation of the stress–strength reliability involving two
independent Weibull distributions is considered. An interval estimation procedure based on …

The focus of stress-strength models is on the evaluation of the probability R= P (Y< X) that
stress Y experienced by a component does not exceed strength X required to overcome it. In …

Because of the exponential distribution assumption, many reliability databases recorded
data in an aggregate way. Instead of individual failure times, each aggregate data point is a …
