        摘要：
        Multivariate one-sided hypotheses testing problems arise frequently in practice. For example, we may wish to compare the economic developments of two regions or compare air pollutions of two regions. In practice, there are often missing values or dropouts. In this case, standard testing procedures based on complete data may not be applicable or may perform poorly if the missing data are discarded. In this talk, we propose several multiple imputation methods for multivariate one-sided testing problem with arbitrary missing data. We also consider constrained inference for nonlinear mixed effects models for longitudinal data.
