title: Estimation of risk as a function of risk factors.
abstract: This paper describes a model which makes allowance for unequal follow-up times in estimating the risk as a function of risk factors. It is the usual exponential model with an instantaneous risk which is assumed to be an exponential function of the risk factors. Computing methods and an extension of the model are given.
