The model-implied covariance matrix from the real parameters
从实际的参数模型隐含的协方差矩阵
参数:misspecM
The model-implied mean from the real and misspecified parameters
该模型隐含的意思是真正的和误设参数

The model-implied covariance matrix from the real and misspecified parameters
该模型隐含的协方差矩阵的实部和误设参数
参数:dfParam
The degree of freedom of the real model
真正的模型自由的程度
参数:fit.measures
The names of indices used to calculate population misfit. There are three types of misfit: 1) discrepancy function ("f0"; see popDiscrepancy), 2) root mean squared error of approximation ("rmsea"; Equation 12 in Browne & Cudeck, 1992), and 3) standardized root mean squared residual ("srmr")
指数计算人口的失配的名称。有三种类型:1)失配的差异函数("f0"; popDiscrepancy),2)均方根误差近似("rmsea"式(12),1992年在布朗和Cudeck的),和3)标准化均方根平方剩余("srmr")

详细信息----------Details----------
The root mean squared error of approximation (RMSEA) is calculated by
的近似误差均方根(RMSEA)的计算方法是
where F_0 is the discrepancy value between two means vectors and covariance matrices (see popDiscrepancy) and df is the degree of freedom in the real model.
F_0是两种手段向量和协方差矩阵(见popDiscrepancy)和df程度的自由,真正的模型之间的差异值。
The standardized root mean squared residual can be calculated by
标准化均方根平方剩余可以计算出
where s_{ij} is the observed covariance between indicators i and j, \hat{σ}_{ij} is the model-implied covariance between indicators i and j, p is the number of indicators.
s_{ij}是观察指标之间的协方差i和j\hat{σ}_{ij}是隐含的模型之间的协方差指标i和j,p是指标的数量。
值----------Value----------
The vector of the misfit indices
的失配指数的向量
