描述----------Description----------
Initial estimates for the parameters in the pdMat objects forming object, which have not yet been initialized, are obtained using the methodology described in Bates and Pinheiro (1998). These estimates may be refined using a series of EM iterations, as described in Bates and Pinheiro (1998). The number of EM iterations to be used is defined in control.
初步估计的参数在pdMat对象形成object,尚未被初始化,使用贝茨和皮涅罗(1998)中描述的方法获得。这些估计可能使用了一系列的EM迭代的细化,贝茨和皮涅伊罗(1998)所述。 EM可用于迭代被定义在control。
用法----------Usage----------
## S3 method for class 'reStruct'
Initialize(object, data, conLin, control, ...)
参数----------Arguments----------
参数:object
an object inheriting from class reStruct, representing a random effects structure and consisting of a list of pdMat objects.
从类继承的对象reStruct,代表随机效应的结构和组成的一个pdMat对象列表。
参数:data
a data frame in which to evaluate the variables defined in formula(object).
在评价formula(object)定义的变量的数据框。
参数:conLin
a condensed linear model object, consisting of a list with components "Xy", corresponding to a regression matrix (X) combined with a response vector (y), and "logLik", corresponding to the log-likelihood of the underlying model.
简明的线性模型中的对象,包括一个组件列表"Xy",相应的回归矩阵(X)结合响应矢量(y),"logLik"对应的底层模型的日志可能性。
参数:control
an optional list with a single component niterEM controlling the number of iterations for the EM algorithm used to refine initial parameter estimates. It is given as a list for compatibility with other Initialize methods. Defaults to list(niterEM = 20).
一个单一的组件niterEM控制迭代的EM算法中使用,以完善的初始参数估计的数目的可选列表。它是作为一个与其他Initialize方法的兼容性列表。 list(niterEM = 20)默认。
参数:...
some methods for this generic require additional arguments. None are used in this method.
这个通用的一些方法需要额外的参数。没有使用这种方法。
值----------Value----------
an reStruct object similar to object, but with all pdMat components initialized.
reStructobject类似对象,所有的pdMat组件,但初始化。
