We propose a new method to address the nonparametric Behrens-Fisher problem, allowing for unequal distribution functions across the two samples. The procedure tests the null hypothesis H 0 : θ = 1 / 2 $/mathcal {H}_0: /theta = /ni...
Intercept Estimation of Semi-Parametric Joint Models in the Context of Longitudinal Data Subject to Irregular Observations [0.03%]
纵向数据半参数联合模型下不规则观察下的截距估计问题研究

Longitudinal data are often subject to irregular visiting times, with outcomes and visit times influenced by a latent variable. Semi-parametric joint models that account for this dependence have been proposed; among these, the Sun model is ...
Impact of Near-Positivity Violations on IPTW-Estimated Marginal Structural Survival Models With Time-Dependent Confounding [0.03%]
近 positivity 违约对基于时间依赖性混淆的时间加权边缘结构生存模型的影响

In longitudinal observational studies, marginal structural models (MSMs) are used to analyze the causal effect of an exposure on the (time-to-event) outcome of interest, while accounting for exposure-affected time-dependent confounding. In ...
Pseudo-Observation Approach for Length-Biased Cox Proportional Hazards Model [0.03%]

Pseudo-observations are used to estimate the expectation of a function of interest in a population when survival data are incomplete due to censoring or truncation. Length-biased sampling is a special case of a left-truncation model, in whi...

With the spread and rapid advancement of black box machine learning (ML) models, the field of interpretable machine learning (IML) or explainable artificial intelligence (XAI) has become increasingly important over the last decade. This is ...
Sparse Canonical Correlation Analysis for Multiple Measurements With Latent Trajectories [0.03%]
具有潜在轨迹的多个测量的稀疏典型相关分析

Canonical correlation analysis (CCA) is a widely used multivariate method in omics research for integrating high-dimensional datasets. CCA identifies hidden links by deriving linear projections of observed features that maximally correlate ...
Non-Markov Nonparametric Estimation of Complex Multistate Outcomes After Hematopoietic Stem Cell Transplantation [0.03%]
基于造血干细胞移植后复杂多状态结局的非马尔可夫非参数估计方法

Often probabilities of nonstandard time-to-event endpoints are of interest, which are more complex than overall survival. One such probability is chronic graft-versus-host disease (GvHD-) and relapse-free survival, the probability of being ...

In modern clinical trials, there is immense pressure to use surrogate markers in place of an expensive or long-term primary outcome to make more timely decisions about treatment effectiveness. However, using a surrogate marker to test for a...
Variable Selection via Fused Sparse-Group Lasso Penalized Multi-state Models Incorporating Molecular Data [0.03%]
基于融合稀疏分组惩罚和分子数据的多状态模型变量选择

Kaya Miah et al.
In multi-state models based on high-dimensional data, effective modeling strategies are required to determine an optimal, ideally parsimonious model. In particular, linking covariate effects across transitions is needed to conduct joint var...
Generalized Bayesian Inference for Causal Effects Using the Covariate Balancing Procedure [0.03%]
基于协变量均衡化的因果效应的广义贝叶斯推断

In observational studies, the propensity score plays a central role in estimating causal effects of interest. The inverse probability weighting (IPW) estimator is commonly used for this purpose. However, if the propensity score model is mis...
