The minimum-diameter partitioning problem (MDPP) seeks to produce compact clusters, as measured by an overall goodness-of-fit measure known as the partition diameter, which represents the maximum dissimilarity between any two objects placed...

Virtually all discussions and applications of statistical mediation analysis have been based on the condition that the independent variable is dichotomous or continuous, even though investigators frequently are interested in testing mediati...
How the 2SLS/IV estimator can handle equality constraints in structural equation models: a system-of-equations approach [0.03%]
基于联立方程的结构方程模型约束条件的两阶段最小二乘法/工具变量估计方法

Parameters in structural equation models are typically estimated using the maximum likelihood (ML) approach. Bollen (1996) proposed an alternative non-iterative, equation-by-equation estimator that uses instrumental variables. Although this...
Should we rely on the Kenward-Roger approximation when using linear mixed models if the groups have different distributions? [0.03%]
在使用线性混合模型时，如果组分布不同，我们应该依赖Kenward-Roger近似吗？

Jaume Arnau et al.
The study explores the robustness to violations of normality and sphericity of linear mixed models when they are used with the Kenward-Roger procedure (KR) in split-plot designs in which the groups have different distributions and sample si...
On the asymptotic standard error of a class of robust estimators of ability in dichotomous item response models [0.03%]

In item response theory, the classical estimators of ability are highly sensitive to response disturbances and can return strongly biased estimates of the true underlying ability level. Robust methods were introduced to lessen the impact of...
Olp: an R package for optimal linear partitions of finite sets of points on the plane [0.03%]
Olp：一个用于在平面上对有限点集进行最优线性划分的R包

Given a set of points on the plane and an assignment of values to them, an optimal linear partition is a division of the set into two subsets which are separated by a straight line and maximally contrast with each other in the values assign...
An accumulator model for responses and response times in tests based on the proportional hazards model [0.03%]
基于比例危险模型的测试中反应和反应时间的累积器模型

Jochen Ranger
Latent trait models for responses and response times in tests often lack a substantial interpretation in terms of a cognitive process model. This is a drawback because process models are helpful in clarifying the meaning of the latent trait...

The difference between two proportions, referred to as a risk difference, is a useful measure of effect size in studies where the response variable is dichotomous. Confidence interval methods based on a varying coefficient model are propose...
Semi-parametric proportional hazards models with crossed random effects for psychometric response times [0.03%]
具有交叉随机效应的心理测量反应时间的半参数比例危险模型
Tom Loeys,Catherine Legrand,Antonio Schettino et al.
Tom Loeys et al.
The semi-parametric proportional hazards model with crossed random effects has two important characteristics: it avoids explicit specification of the response time distribution by using semi-parametric models, and it captures heterogeneity ...

Missing values are a practical issue in the analysis of longitudinal data. Multiple imputation (MI) is a well-known likelihood-based method that has optimal properties in terms of efficiency and consistency if the imputation model is correc...
