A common problem in formulating models for causal effects under binary causal models is the variation dependence between the causal parameters and the commonly-used nuisance models. Such causal models include the structural mean model for the conditional relative risk and risk difference, the binary instrumental variable model, the binary structural nested mean model, and so forth. We address this problem by proposing novel nuisance models based on the conditional odds product. These novel nuisance models facilitate maximum-likelihood estimation, but also permits doubly-robust estimation for the causal parameters of interest.
