A modification of the EM algorithm is proposed for situations in which the maximization of the "complete data" likelihood function does not have a closed-form solution. Self-consistency of the modified algorithm is established. Application to carcinogenicity experiments is illustrated, and the results of a simulation study comparing the original and modified versions indicate that use of the proposed modification can lead to significant computational savings.
