SUMMARY A nonparametric estimator for the survival function, accommodating censored survival times and uncertainty in the assignment of cause of death, is proposed. For example, in a carcinogenicity experiment the data on each animal may consist of a

The distribution of the maximum likelihood estimates of virtually safe levels of exposure to environmental chemicals is derived by using large-sample theory and Monte Carlo simulation according to the Armitage-Doll multistage model. Using historical

SUMMARY Cohort mortality data is represented by a probabilistic combination of competing risks (diseases). Each risk is described by an age-at-death distribution and a net probability of occurrence. This representation is illustrated by a set of path

A stochastic model for the growth of a cell population is proposed, and is studied by means of simulations on a digital computer. In order to fit this model to experimental data, repeated computer simulations are performed and the 'distance' between
