我的生物统计研究涵盖了两个领域：倾向beplay苹果手机能用吗得分分析和纵向和生存数据的联合分析。

倾向评分分析是调整混杂的重要方法，并且在观察性研究中广泛使用，这构成了有关医疗治疗有效性的大部分已发表证据。我对倾beplay苹果手机能用吗向分析分析的研究集中在改进的方法上，以进行有效的估计，准确的方差估计和客观平衡检查。我还将思想扩展到广义倾向分析分析，该分析研究了连续暴露变量的因果关系。鉴于倾向得分在因果推断的广泛研究领域中发挥的基本作用，因此可以在各种因果应用中以创新的方式扩展这种方法。beplay苹果手机能用吗

Most longitudinal cohort studies collect both longitudinal data and time to event data. These two types of data often need to be analyzed jointly to reveal the relationships between them. My research targets two aspects of the problem. First, when the trajectory of the longitudinal data is nonlinear, typical methods for joint analysis may become computationally prohibitive due to the intractable high-dimensional integrals in the likelihood. I am developing new models and computational methods to address this computational challenge. Second, the longitudinal data may be used to predict the time to event in a prediction model. This is a new research area called dynamic prediction, as the prediction may change over time as more longitudinal data become available. Various issues need to be studied, including model formulation, estimation and prediction error assessment.
