This paper reports on a simulation study that evaluated the performance of five structural equation model test statistics appropriate for categorical data. Both Type I error rate and power were investigated. Different model sizes, sample si...
Evaluation of dominance-based ordinal multiple regression for variables with few categories [0.03%]
基于支配的序数多重回归评估用于具有少量类别的变量的有效性
Carol M Woods
Carol M Woods
Dominance-based ordinal multiple regression (DOR) is designed to answer ordinal questions about relationships among ordinal variables. Only one parameter per predictor is estimated, and the number of parameters is constant for any number of...
A Monte Carlo study comparing PIV, ULS and DWLS in the estimation of dichotomous confirmatory factor analysis [0.03%]
PIV、ULS和DWLS在二分数据验证性因素分析估计中的比较——基于蒙特卡洛研究

We conducted a Monte Carlo study to investigate the performance of the polychoric instrumental variable estimator (PIV) in comparison to unweighted least squares (ULS) and diagonally weighted least squares (DWLS) in the estimation of a conf...
The linear transformation model with frailties for the analysis of item response times [0.03%]
带有脆弱性因子的线性变换模型在项目反应时间分析中的应用
Chun Wang,Hua-Hua Chang,Jeffrey A Douglas
Chun Wang
The item response times (RTs) collected from computerized testing represent an underutilized source of information about items and examinees. In addition to knowing the examinees' responses to each item, we can investigate the amount of tim...
Angoff's delta method revisited: improving DIF detection under small samples [0.03%]
安格夫的DELTA法再探：小样本条件下提高DIF检测力

David Magis
Most methods for detecting differential item functioning (DIF) are suitable when the sample sizes are sufficiently large to validate the null statistical distributions. There is no guarantee, however, that they will still perform adequately...

Classical reliability theory assumes that individuals have identical true scores on both testing occasions, a condition described as stable. If some individuals' true scores are different on different testing occasions, described as unstabl...
Continuous time modelling with individually varying time intervals for oscillating and non-oscillating processes [0.03%]
具有个人变化时间间隔的连续时间模型在振荡和非振荡过程中的应用

Manuel C Voelkle
When designing longitudinal studies, researchers often aim at equal intervals. In practice, however, this goal is hardly ever met, with different time intervals between assessment waves and different time intervals between individuals being...

A substantial school in the philosophy of science identifies Bayesian inference with inductive inference and even rationality as such, and seems to be strengthened by the rise and practical success of Bayesian statistics. We argue that the ...
Using the Tukey-Kramer omnibus test in the Hayter-Fisher procedure [0.03%]
利用Tukey-Kramer统合检验的Hayter-Fisher程序
Scott J Richter,Melinda H McCann
Scott J Richter
Using Tukey-Kramer versus the ANOVA F-test as the omnibus test of the Hayter-Fisher procedure for comparing all pairs of normally distributed means, when sample sizes are unequal, is investigated. Simulation results suggest that using Tukey...
A clusterwise simultaneous component method for capturing within-cluster differences in component variances and correlations [0.03%]
一种聚类同时成分法，用于捕捉组件方差和相关性在集群内的差异

Kim De Roover et al.
This paper presents a clusterwise simultaneous component analysis for tracing structural differences and similarities between data of different groups of subjects. This model partitions the groups into a number of clusters according to the ...
