描述----------Description----------
The RtreemixStats class contains the (weighted, log) likelihoods for a given dataset (specified by the parent class) derived from the probability distribution induced by an underlying mutagenetic trees mixture model.
类RtreemixStats包含一个给定的数据集（加权，log）来自一个潜在的致突变树木混合模型诱导的概率分布的似然性（由指定的父类）。
类的对象----------Objects from the Class----------
Objects can be created by calls of the form new("RtreemixStats", Data, Model, LogLikelihoods, WLikelihoods). The class RtreemixStats extends the RtreemixData class and specifies (log, weighted) likelihoods for these data derived from a given RtreemixModel. The number of the genetic events in the patterns from the given dataset (Data) has to be equal to the number of genetic events in the branchings from the mixture model given by the slot Model. When having the weighted likelihoods, one can easily derive the responsibilities of the model components in Model for generating the patterns in the specified dataset (Data).
创建对象可以通过检测的形式new("RtreemixStats", Data, Model, LogLikelihoods, WLikelihoods)。类RtreemixStats扩展从一个给定的RtreemixDataRtreemixModel类和指定（log，加权）获得这些数据的似然性。在给定的数据集模式的遗传事件（Data）等于在从插槽Model混合模型的分枝的遗传事件。加权似然性时，人们可以很容易地推导出产生的模式，在指定的数据集（Model）Data模型组件的责任。
The Data is an RtreemixData object that specifies the patterns for which the likelihoods are calculated.
Data是RtreemixData对象指定的似然性的计算模式。
The Model is an RtreemixModel object that specifies the mutagenetic trees mixture model used for deriving the likelihoods of the given data.
Model是RtreemixModel对象，指定用于推导给定数据的似然性，致突变的树木混合模型。
The LogLikelihoods is a numeric vector that contains the log-likelihoods of the patterns in Data. Its length equals the sample size, i.e. the number of patients in Data.
LogLikelihoods是一个数字vector包含log的模式在Data似然性。它的长度等于样本大小，即患者Data的数量。
The WLikelihoods is a numeric matrix that specifies the weighted likelihoods of each pattern in the given dataset Data. The number of columns in WLikelihoods equals the number of tree components in Model and the number of rows equals the number of patients in Data.
WLikelihoods是一个数字matrix指定在给定的数据集Data每种模式的加权似然性。数列在WLikelihoods等于Model树组件的数量和行数等于患者Data的数量。
