求助：Mplus统计软件
有人知道Mplus吗？哪里可以下载？Mplus 是最新统计建模软件，可进行latent growth mixture modeling 或者 latent class modeling. 换句话说，Mplus 更注重对人的分析。比如，某样本就受某药物治疗（or other treatment，intervention et al.)，研究者想知道是否有潜在样本（latent class, or subgroup）对此治疗反应良好，一般，或差。
The generality of the Mplus modeling framework comes from the unique use of both continuous and categorical latent variables. Continuous latent variables are used to represent factors corresponding to unobserved constructs, random effects corresponding to individual differences in development, random effects corresponding to variation in coefficients across groups in hierarchical data, frailties corresponding to unobserved heterogeneity in survival time, liabilities corresponding to genetic susceptibility to disease, and latent response variable values corresponding to missing data. Categorical latent variables are used to represent latent classes corresponding to homogeneous groups of individuals, latent trajectory classes corresponding to types of development in unobserved populations, mixture components corresponding to finite mixtures of unobserved populations, and latent response variable categories corresponding to missing data.
适用版可从[url]http://www.statmodel.com[/url] 下载，但适用版中，dependent variables 最多为6个，independent variables 最多2个。 那位大侠又免费的呀？我也想要。
