In this article, we directly questioned the common practice in growth mixture model (GMM) applications that exclusively rely on the fitting model without covariates for GMM class enumeration. We provided theoretical and simulation evidence ...
Using Potential Outcomes to Understand Causal Mediation Analysis: Comment on [0.03%]
运用潜在结果理解因果中介分析：对《关于因果中介分析》一文的评论

In this commentary, we demonstrate how the potential outcomes framework can help understand the key identification assumptions underlying causal mediation analysis. We show that this framework can lead to the development of alternative rese...
Estimating Latent Variable Interactions With Non-Normal Observed Data: A Comparison of Four Approaches [0.03%]
非正态观测数据下的潜在变量交互作用的估计：四种方法的比较
Heining Cham,Stephen G West,Yue Ma et al.
Heining Cham et al.
A Monte Carlo simulation was conducted to investigate the robustness of four latent variable interaction modeling approaches (Constrained Product Indicator [CPI], Generalized Appended Product Indicator [GAPI], Unconstrained Product Indicato...

Peter M Bentler
Molenaar (2003, 2011) showed that a common factor model could be transformed into an equivalent model without factors, involving only observed variables and residual errors. He called this invertible transformation the Houdini transformatio...
A Third Moment Adjusted Test Statistic for Small Sample Factor Analysis [0.03%]
用于小样本因素分析的第三个矩调整检验统计量
Johnny Lin,Peter M Bentler
Johnny Lin
Goodness of fit testing in factor analysis is based on the assumption that the test statistic is asymptotically chi-square; but this property may not hold in small samples even when the factors and errors are normally distributed in the pop...
Conceptualizing and Estimating Process Speed in Studies Employing Ecological Momentary Assessment Designs: A Multilevel Variance Decomposition Approach [0.03%]
生态时刻评估设计中过程速度的概念化与估计：多层次方差分解方法

Researchers have been making use of ecological momentary assessment (EMA) and other study designs that sample feelings and behaviors in real time and in naturalistic settings to study temporal dynamics and contextual factors of a wide varie...

Booil Jo et al.
Mediation analysis uses measures of hypothesized mediating variables to test theory for how a treatment achieves effects on outcomes and to improve subsequent treatments by identifying the most efficient treatment components. Most current m...
A Tutorial and Case Study in Propensity Score Analysis: An Application to Estimating the Effect of In-Hospital Smoking Cessation Counseling on Mortality [0.03%]
倾向得分分析的教程和案例研究：一项有关住院期间戒烟咨询对死亡率影响估计的研究应用

Propensity score methods allow investigators to estimate causal treatment effects using observational or nonrandomized data. In this article we provide a practical illustration of the appropriate steps in conducting propensity score analyse...
An Introduction to Propensity Score Methods for Reducing the Effects of Confounding in Observational Studies [0.03%]
倾向分值在观察性研究中减少混淆因素影响的介绍方法

The propensity score is the probability of treatment assignment conditional on observed baseline characteristics. The propensity score allows one to design and analyze an observational (nonrandomized) study so that it mimics some of the par...
