18. Testes de significancia repetidos em analise de sobrevivencia
The main objective of this work is to elaborate a detailed exposition of the theory of repeated significance tests, with particular emphasis on non parametric tests used in Survival Analysis. A second objective is to study and use in applications the somehow new Weighted Kaplan Meier statistic that was created to compare survival in two populations. This sta

19. Desenvolvimento somÃtico e sensÃrio-motor e padrÃo do consumo alimentar, em ratos: efeitos do tratamento com inibidor de recaptaÃÃo da serotonina durante o perÃodo de crescimento rÃpido do encÃfalo
It was investigated in this work the influences of the treatment with selective serotonin reuptake inhibitor, over the reflex-ontogeny, somatic maturation and adult pattern of food intake. Male Wistar rats were divided in groups, receiving daily, from 1st to 21st day of life, the following treatments, s.c.: Ingenuous (Ing, n=26), any treatment; Saline (Sal,

20. The use of a Kolmogorov--Smirnov type statistic in testing hypotheses about seasonal variation.
This paper presents a non-parametric method for testing departures from a uniform seasonal variation in incidence of disease. The method may be used either with exact dates of incidence when they are available or with monthly totals. It is equally valid for sinusoidal and non-sinusoidal departures from uniformity. A simulation study shows it to be much more

21. Combined use of non-invasive techniques to predict pulmonary arterial pressure in chronic respiratory disease.
The value of non-invasive procedures for predicting pulmonary arterial pressure was investigated in 370 patients with chronic obstructive lung diseases and in 73 with fibrosing alveolitis in a combined study at nine centres in six European countries. Measurements included forced expiratory volume in one second, arterial blood gas tensions, standard electroca

22. Using Allele Frequencies and Geographic Subdivision to Reconstruct Gene Trees within a Species: Molecular Variance Parsimony
We formalize the use of allele frequency and geographic information for the construction of gene trees at the intraspecific level and extend the concept of evolutionary parsimony to molecular variance parsimony. The central principle is to consider a particular gene tree as a variable to be optimized in the estimation of a given population statistic. We prop
