    Model checking for a general linear model with nonignorable missing covariates

    In this paper, we investigate the model checking problem for a general linear model with nonignorable missing covariates. We show that, without any parametric model assumption for the response probability, the...

    Quasi-likelihood estimation of average treatment effects based on model information

    In this paper, the estimation of average treatment effects is considered when we have the model information of the conditional mean and conditional variance for the responses given the covariates. The quasi-li...
