Description: The package performs estimation and testing of the
        treatment effect in a 2-group randomized clinical trial with a
        quantitative or dichotomous endpoint. The method is a special
        case of Robins, Rotnitzky, and Zhao (1994, JASA). It improves
        efficiency by leveraging baseline predictors of the endpoint.
        The method uses inverse probability weighting to provide
        unbiased estimation when the endpoint is missing at random.
