The Challenger disaster evoked a national resolve to reduce the risk of future space flight tragedies. A part of that resolve was to estimate the present risks as accurately as possible. This article illustrates and compares several such ways of inco

SUMMARY Root systems of seedlings of 14 Victorian eucalypts are described. Their root growth is compared with their shoot growth on the basis of length, oven-dry weight, and fresh weight. The species native to dry areas develop a long tap-root with f

In the application of factorial experiments in industry, it is often necessary to apply the factors sequentially. For 2 p experiments in which (a) multiple testing on each experimental unit is possible and not degrading, (b) the effects of the factor

The purpose of this paper is to make the reader aware of the applicability and advantage of a particular mathematical model. The application is typified by an example and the advantage is via confidence intervals; that is, shorter confidence interval

SUMMARY A study using seeds of 23 Victorian eucalypts has indicated that most seed-lots of some species, a few of others, and possibly none of some species require light for satisfactory germination. Germination of some seeds appears to be inhibited

Bayes confidence intervals for the hypergeometric parameter denoting the number of defectives in a lot can be obtained from Neyman confidence intervals or from the cumulative hypergeometric or cumulative binominal when the prior distributions are cer

In [1] a design, referred to as a Factor Sequencing Design (FSD), and analysis are presented for 2p factorial experiments where the factors are applied sequentially and where order of application may be of importance. The number of units required for

The purpose of this paper is to demonstrate the application of Bayesian procedures to the field of reliability. First, the behavior of a family of Bayesian a posteriori distributions is examined pictorially and described asymptotically by a limit the

Some attribute sampling plans are presented based on the theory of runs in which a batch or process is accepted if a run of s successes is observed in a fixed number n of trials. The operating characteristic (OC) and expected number of trials (ENT) c
