Summary. In the two-sample comparison of survival times with long-term survivors, the overall difference between the two distributions reflects differences occurring in early follow-up for susceptible subjects and in long-term follow-up for nonsuscep

The ordered logrank tests of [1]for ordered alternatives are considered in the case of a continuous covariate. A reformulation of the test statistics using rankings of the covariate is first introduced, which leads to a generalization of the tests to

In analysing a clinical trial with the logrank test, the hazards between the two groups are usually assumed to be proportional. Nevertheless, this hypothesis is no longer valid with unobserved covariates. As a consequence, there is a loss of power of

Two-phase stratification sampling with unequal selection probabilities is a relatively cost-efficient strategy to address problems on a nationwide basis and to perform comparative analyses of specific subgroups. This was the case with the ACSF survey

A new rank test family is proposed to test the equality of two multivariate failure times distributions with censored observations. The tests are very simple: they are based on a transformation of the multivariate rank vectors to a univariate rank sc

In a questionnaire survey of 9591 men between 17 and 27 years of age, there was an association between present handedness score and report of an earlier injury causing a temporary shift of hand use. The proportion of weak right-handers was higher amo

Fetal toxicity of cadmium (Cd) is well documented in rodents. However, little information is available regarding the human fetus. To investigate the effect of low levels of Cd on the human placenta and the consequences on birthweight, we conducted a

The succession procedure is a new method for group sequential analysis based on a succession of significant tests. In this paper, the procedure is extended by the addition of a lower boundary, which allows the early acceptance of the null hypothesis
