Abstract
Summary: Regression models of the proportional hazard type are applied to investigate the effect of certain covariates on the survival function of some cancer patients. The censored survival data for these patients were taken from a survey conducted by the Queensland Melanoma Project through which there are available histories of all malignant melanoma cases in Queensland for the period 1963–1969; follow‐up data on these cases were considered up to mid‐1976. One of the results of the survival analysis shows that the well‐known empirical observation that women have a better prognosis than men can be explained by the existence of a significant interaction between sex and the anatomical site of the lesion.Keywords
