A guideline for the statistical analysis of compositional data in immunology [0.03%]
免疫学中组成性数据统计分析指南

Jinkyung Yoo et al.
The study of immune cellular composition has been of great scientific interest in immunology because of the generation of multiple large-scale data. From the statistical point of view, such immune cellular data should be treated as composit...

The p-value calculation methods for the partial and semi-partial correaltion coefficients were proposed by Cohen et al. (2003) and Kim (2015). The method of Cohen et al. (2003) depends on a single and identical statistic for both partial an...
Ranking subjects based on paired compositional data with application to age-related hearing loss subtyping [0.03%]
基于配对组成数据的学科排名及其在年龄相关性听力损失分型中的应用

Jin Hyun Nam et al.
Analysis approaches for single compositional data are well established; however, effective analysis strategies for paired compositional data remain to be investigated. The current project was motivated by studies of age-related hearing loss...
Practice of causal inference with the propensity of being zero or one: assessing the effect of arbitrary cutoffs of propensity scores [0.03%]
因果推断中处理倾向得分为0或1的情形——评估任意截止值对倾向得分的影响
Joseph Kang,Wendy Chan,Mi-Ok Kim et al.
Joseph Kang et al.
Causal inference methodologies have been developed for the past decade to estimate the unconfounded effect of an exposure under several key assumptions. These assumptions include, but are not limited to, the stable unit treatment value assu...

Simon's two-stage designs are frequently used in phase II single-arm trials for efficacy studies. In safety studies, a main concern is that there may be too many patients who experience an adverse event. We show that Simon's two-stage desig...

In nested case-control studies, the most common way to make inference under a proportional hazards model is the conditional logistic approach of Thomas (1977). Inclusion probability methods are more efficient than the conditional logistic a...
ppcor: An R Package for a Fast Calculation to Semi-partial Correlation Coefficients [0.03%]

Lack of a general matrix formula hampers implementation of the semi-partial correlation, also known as part correlation, to the higher-order coefficient. This is because the higher-order semi-partial correlation calculation using a recursiv...
