    Projection-based Consistent Test for Linear Regression Model with Missing Response and Covariates

    In recent years, there has been a large amount of literature on missing data. Most of them focus on situations where there is only missingness in response or covariate.

    Variable selection of generalized regression models based on maximum rank correlation

    In this paper, we investigate the variable selection problem of the generalized regression models. To estimate the regression parameter, a procedure combining the rank correlation method and the adaptive lasso...

    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...

    Semiparametric analysis of longitudinal data with informative observation times

    In many longitudinal studies, observation times as well as censoring times may be correlated with longitudinal responses. This paper considers a multiplicative random effects model for the longitudinal respons...
