译者：生物统计家园网 机器人LoveR
描述----------Description----------
Returns information on the construction of the treelet hierarchical tree on which the basis functions are supported.
返回信息的建设的treelet层次树的基础功能的支持。
用法----------Usage----------
Build_JTree(C, cc, maxlev, whichsave)
参数----------Arguments----------
参数：C
the covariance matrix of the data. For example, if using this function on genetics data to improve estimates of heritability, as in the Crossett et al arXiv paper, this argument will be the estimated additive genetic relationship matrix \hat{A}.
数据的协方差矩阵。例如，如果使用此功能的遗传学资料，以提高估计的遗传，克罗塞特等arXiv纸，这种说法是估计加性遗传关系矩阵\hat{A}。
参数：cc
the correlation matrix of the data.
数据的相关矩阵。
参数：maxlev
the maximum height of the tree. This must be an integer between 1 and nrow(X)-1.
树的最大高度。这必须是一个整数1和nrow(X)-1之间。
参数：whichsave
a vector containing the levels of the tree, specified as integers between 1 and maxlev, for which you want to save the basis functions and the covariance matrix.
一个向量，包含水平的树，指定为整数1和maxlev，你要保存的基础功能和协方差矩阵。
值----------Value----------
a list with components
与组件的列表
参数：Zpos
A matrix of dimension maxlev x 2. Each row records which two nodes/clusters of the tree were combined at each step in its construction.
的矩阵尺寸maxlev×2。的每一行的记录，其中两个节点/合并树簇在其结构中的每个步骤。
参数：T
This is a list with maxlev elements, where each element is a 2x2 Jacobi rotation matrix for each step of the treelet algorithm.
这是一个maxlev元素，其中每个元素是一个2×2的Jacobi旋转矩阵每个步骤的treelet算法的列表。
参数：PCidx
A matrix of dimension maxlev x 2, where each row is a permutation of (1,2) indicating which of the two nodes/clusters merged at that step is the sum variable (value of 1) and which is the difference (value of 2).
A矩阵的维度maxlev×2，其中的每一行是一个置换(1,2)表示合并在该步骤中的两个节点/聚类的总和变量（值1）和它的区别是（值为2）。
参数：all_nodes
A matrix of dimension maxlev x nrow(X) giving node/cluster labels at each step of the treelet algorithm. A label of zero indicates a node/cluster that was merged with another node/cluster and was the difference variable.
维的矩阵maxlevXnrow(X)给节点/聚类标签在每一步的treelet算法。零标签表示节点/聚类与另一个节点/聚类和合并的差异变量。
参数：TreeCovs
This is a list with maxlev elements. Only those elements that are specified in the whichsave argument will be non-null entries in the list. For the non-null entries, this is the covariance matrix calculated at that level of the tree. The covariances in this matrix are those between the weights (orthogonal projections onto local basis vectors) in the basis expansion of the data vector.
这是maxlev元素的列表。只有那些元素中指定的whichsave参数非空列表中的条目。对于非空条目，这是在该级别的树的协方差矩阵计算。该矩阵中的协方差的权重之间（当地基矢量的正交投影）的数据矢量的基础上扩大。
