Exponentiality test based on Renyi distance between equilibrium distributions

ABSTRACT

On the basis of Csiszar's φ-divergence discrimination information, we propose a measure of discrepancy between equilibriums associated with two distributions. Proving that a distribution can be characterized by associated equilibrium distribution, a Renyi distance of the equilibrium distributions is constructed that made us to propose an EDF-based goodness-of-fit test for exponential distribution. For comparing the performance of the proposed test, some well-known EDF-based tests and some entropy-based tests are considered. Based on the simulation results, the proposed test has better powers than those of competing entropy-based tests for the alternatives with decreasing hazard rate function. The use of the proposed test is evaluated in an illustrative example.

The Making of COBRS 2.0

Abstract

Recently introduced advances in microcomputer technology offer opportunities for improving child welfare agencies' access to powerful case assessment and program evaluation tools. This paper discusses the process of fitting a child behavior outcome measurement system to a menu driven microcomputer program. Traditional strategies for measuring outcome effectiveness, managerial priorities and operational constraints are examined in terms of their bearing on the introduction of new microcomputer technology. The developmental process is traced to show how these factors influenced the addition of a number of user options to the basic program to enhance its adaptability to specific agency needs. Initial user feedback indicated general satisfaction with the basic program and the applicability of its output, little or no experimentation, as yet, in adapting the system, and, a minor need to adjust the sequencing of operator activities to better fit the realities of agency work rhythms.     

‘The Rule of Men Entirely Great’: Republicanism,Ritual, and Richelieu in Melville’s ‘The Two Temples’

Abstract

This article explores the complex and multifarious reasons behind Herman Melville’s decision to refer to the English playwright Edward Bulwer-Lytton’s 1839 work Richelieu, or The Conspiracy in his 1854 diptych ‘The Two Temples’. It responds to a critical consensus that has seen the reference merely as a sarcastic attack on William Macready (whose rivalry with the American actor Edwin Forrest was the nominal cause of the bloody 1849 Astor Place Riot in New York), by contextualizing the play within traditions of antebellum American Anglophilia. By using a combination of new critical work on Anglo-Americanism and anthropological ritual theory, I show how Bulwer-Lytton’s play was significant to Melville’s artistic development. In particular, I demonstrate how the play influenced his increasing engagement with republican and theatrical forms of expression that emphasized the importance of filial relationships between America and Britain in a period of increasing hostility between the two nations.     

Locally best invariant test for outliers in a gamma type distribution

It is shown that the locally best invariant test for the existence of outliers for scale parameters of the gamma distribution is given by Bartholomew's test for exponentiality which is the ratio of the sum of squares of the data to the square of the sample mean. The optimality robustness, including null and nonnull robustness of the test is shown. A small simulation study to compare the power among the other eight competitive tests for testing exponentiality is performed. It is seen that the locally best invariant test is not always best but is reasonably good. It is slightly better than Cochran's test and suffers less from the limiting masking effect.

Calculation of the expected lifetime lost due to an extra risk

Methods are given for estimating the average years of life lost when a person is discovered to be at risk from an extra hazard. The methods use the probability per year of the extra risk striking, and the mean and standard deviation of lifetime in the absence of the risk. The formulae are simple enough that only a hand‐held calculator is needed.
