Under multiple matching, relative risk from a rare disease is estimated in a retrospective design. Maximum likelihood estimation is carried out using an unconditional probability model. In addition, this model is used to derive a new estimator of relative risk which is noniterative but is as efficient, asymptotically, as the maximum likelihood estimator.
