We consider linear transformation models applied to right censored survival data with a change-point in the regression coefficient based on a covariate threshold. We establish consistency and weak convergence of the nonparametric maximum likelihood estima-tors. The change-point parameter is shown to be n-consistent, while the remaining parameters are shown to have the expected root-n consistenc...
Two challenging problems in the clinical study of cancer are the characterization of cancer subtypes and the classification of individual patients according to those subtypes. Statistical approaches addressing these problems are hampered by population heterogeneity and challenges inherent in data integration across high-dimensional, diverse covariates. We have developed a survival-supervised la...
در حالت کلی معادلات دیفرانسیل با مقادیر اولیه را نمی توان دیفرانسیل می توان جواب طیف وسیعی از مسائل کاربردی را مشخص نمود با روش های تئوری حل نمود، لذا با حل عددی معادلات یک حالت خاص از مسأله مقدار اولیه، مسأله ای به فرم: y^=f(x,y) , y(a)=?, y^ (a)=?^^ است که مشتق اول در آن ظاهر نمی شود. این معادلات طیف وسیعی از پدیده های اطراف ما را شامل می شود، مثلاً معادلاتی که دارای جواب نوسانی هستند از ...

In many medical studies, event times are recorded in an interval-censored (IC) format. For example, in numerous cancer trials, time to disease relapse is only known to have occurred between two consecutive clinic visits. Many existing modeling methods in the IC context are com-putationally intensive and usually require numerous assumptions that could be unrealistic or difficult to verify in pra...
