Peter F Thall et al.
The problem of comparing several experimental treatments to a standard arises frequently in medical research. Various multi-stage randomized phase II/III designs have been proposed that select one or more promising experimental treatments a...
Bayesian Experimental Design for Long-Term Longitudinal HIV Dynamic Studies [0.03%]
纵向HIV动态长期实验的贝叶斯设计方法研究

The study of HIV dynamics is one of the most important developments in recent AIDS research for understanding the pathogenesis of HIV-1 infection and antiviral treatment strategies. Currently a large number of AIDS clinical trials on HIV dy...
Kernel Smoothing Density Estimation when Group Membership is Subject to Missing [0.03%]
分组情况缺失下的核密度估计方法研究
Wan Tang,Hua He,Douglas Gunzler
Wan Tang
Density function is a fundamental concept in data analysis. Nonparametric methods including kernel smoothing estimate are available if the data is completely observed. However, in studies such as diagnostic studies following a two-stage des...
Semiparametric inference of proportional odds model based on randomly truncated data [0.03%]
基于随机截断数据的比例优势模型的半参数推断
Rajeshwari Sundaram
Rajeshwari Sundaram
This paper studies the estimation in the proportional odds model based on randomly truncated data. The proposed estimators for the regression coefficients include a class of minimum distance estimators defined through weighted empirical odd...
Dimension reduced kernel estimation for distribution function with incomplete data [0.03%]
缺失数据下分布函数的降维核估计方法研究
Zonghui Hu,Dean A Follmann,Jing Qin
Zonghui Hu
This work focuses on the estimation of distribution functions with incomplete data, where the variable of interest Y has ignorable missingness but the covariate X is always observed. When X is high dimensional, parametric approaches to inco...

We consider the recent history functional linear models, relating a longitudinal response to a longitudinal predictor where the predictor process only in a sliding window into the recent past has an effect on the response value at the curre...

In clinical trials, several competing treatments are often carried out in the same trial period. The goal is to assess the performances of these different treatments according to some optimality criterion and minimize risks to the patients ...
Best Invariant and Minimax Estimation of Quantiles in Finite Populations [0.03%]
有限总体中分位数的优良不变和极小极大估计
Yaakov Malinovsky,Yosef Rinott
Yaakov Malinovsky
The theoretical literature on quantile and distribution function estimation in infinite populations is very rich, and invariance plays an important role in these studies. This is not the case for the commonly occurring problem of estimation...
Quasi- and pseudo-maximum likelihood estimators for discretely observed continuous-time Markov branching processes [0.03%]
连续时间马尔可夫分枝过程中离散观测下的伪概最大似然估计量及准概最大似然估计量
Rui Chen,Ollivier Hyrien
Rui Chen
This article deals with quasi- and pseudo-likelihood estimation in a class of continuous-time multi-type Markov branching processes observed at discrete points in time. "Conventional" and conditional estimation are discussed for both approa...
Permutational Multiple Testing Adjustments With Multivariate Multiple Group Data [0.03%]
多元多组数据的排列多次检验校正方法
James F Troendle,Peter H Westfall
James F Troendle
We consider the multiple comparison problem where multiple outcomes are each compared among several different collections of groups in a multiple group setting. In this case there are several different types of hypotheses, with each specify...
