Variants of a linear logistic model are used to analyze 2-year survival proportions for 246 children treated for neuroblastoma. The analysis shows that age and stage (extent) of disease at diagnosis are both important factors in determining chances for survival, even after adjusting for the effects of the other. Estimation of prognosis is facilitated by curves relating the probability of survival to age (up to 5 years) for each of 5 stages.
