Mplus建模框架
建模数据的目的是以简单的方式描述数据结构,便于理解和解释。本质上,数据建模相当于变量之间的一组关系。下图表示了在Mplus建模中的关系类型。矩形表示观测变量,观测变量可以是结果变量或背景变量。背景变量为X,连续和截尾结果变量为y,二元、有序范畴(序数),无序分类(名词)和计数结果变量为u。圆圈代表潜变量。允许连续变量和类别变量,连续潜变量为f,分类潜变量为c。

Mplus is a statistical modeling program that provides researchers with a flexible tool to analyze their data. Mplus offers researchers a wide choice of models, estimators, and algorithms in a program that has an easy-to-use interface and graphical displays of data and analysis results. Mplus allows the analysis of both cross-sectional and longitudinal data, single-level and multilevel data, data that come from different populations with either observed or unobserved heterogeneity, and data that contain missing values. Analyses can be carried out for observed variables that are continuous, censored, binary, ordered categorical (ordinal), unordered categorical (nominal), counts, or combinations of these variable types. In addition, Mplus has extensive capabilities for Monte Carlo simulation studies, where data can be generated and analyzed according to any of the models included in the program.
