Abstract
The objective of the paper is twofold: (1) to provide insight on the simplified MVK model of carcinogenesis by revealing the relationship between the Armitage-Doll two-stage model (ADT model) and the simplified MVK model; and (2) to extend the ADT model to one with time-varying (piece-wise constant) parameters. It is shown that the simplified MVK model is a special case of the Armitage-Doll two-stage model , and many applications of the simplified MVK model involving intermittent exposures or exposures to different compounds in different time periods can be derived easily from the ADT model with piece-wise constant parameters. The limitations of the ADT model are discussed. (Copyright (c) 1993 Society for Risk Analysis.)
