Simulation results are reported on methods that allow both within group and between group heteroscedasticity when testing the hypothesis that independent groups have identical regression parameters. The methods are based on a combination of extant techniques, but their finite-sample properties have not been studied. Included are results on the impact of removing all leverage points or just bad ...
The basic problem discussed here is the exploitation of symmetry in solving linear systems of equations which are equivariant under a permutation of the indices. It is essentially an overview of the method given in 11] and 10], augmented by a careful discussion of the case of xed points, which was left untreated in these articles.
OBJECTIVES The level of environmental contamination generated during preparation and administration of hazardous drugs using different valve closed-systems and their combinations was compared. The actual impact on the overall time of preparation of cytostatics and the economic cost of the different modalities were also compared. METHODS Comparative study of the preparation of fluorescein mixt...
An autoradiographic study has been made of mouse femora from birth to one year of age. Tritiated thymidine was used to study the proliferative rate of various skeletal tissues. The labeling index of the periosteum was found to be highest at birth (0.085). At 8 weeks of age the index fell sharply to 0.007 and remained low throughout the entire period of study. Chondro-osteogenic cells of the per...
The last decade has seen a dramatic increase in general interest in and research into vitamin D, with many athletes now taking vitamin D supplements as part of their everyday dietary regimen. The most recognized role of vitamin D is its regulation of calcium homeostasis; there is a strong relationship between vitamin D and bone health in non-athletic individuals. In contrast, data have consiste...
