Comparisons of Lognormal Population Means
Comparisons of two lognormal population means are investigated. For large samples, the conventional test for significance of the population means is the ordinary Student /-test with normal critical value. By Chen and Loh's result (Ann. Statist. 20 (1992)), however, the transformed i-test based on legdata is asymptotically more powerful than the ordinary i-test. In this paper, a new power transf...
متن کاملDeterministic and Evolutionary Extraction of Delta-Lognormal Parameters: Performance Comparison
A theory, called the Kinematic Theory of Rapid Human Movement, was proposed a few years ago to analyze rapid human movements, called the Kinematic Theory of Rapid Human Movements, based on a delta-lognormal equation that globally describes the basic properties of the velocity profiles of an end-effector using seven parameters. This realistic model has been very useful for proposing original sol...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولInterval estimates for the ratio and difference of two lognormal means.
Health research often gives rise to data that follow lognormal distributions. In two sample situations, researchers are likely to be interested in estimating the difference or ratio of the population means. Several methods have been proposed for providing confidence intervals for these parameters. However, it is not clear which techniques are most appropriate, or how their performance might var...
