描述----------Description----------
This package provides the following approaches of multidimensional scaling (MDS) based on stress minimization by means of majorization (smacof): Simple smacof on symmetric dissimilarity matrices, smacof for rectangular matrices (unfolding models), smacof with constraints on the configuration, three-way smacof for individual differences (including constraints for idioscal, indscal, and identity), and spherical smacof (primal and dual algorithm). Each of these approaches is implemented in a metric and nonmetric manner including primary, secondary, and tertiary approaches for tie handling.
这个包提供了以下方法多维尺度(MDS)的基础上通过的的优超(smacof):简单的smacof对称的相异矩阵的压力最小,smacof长方矩阵(展开模型),三路与配置的限制,smacof对于个体差异(包括为idioscal的,INDSCAL的,和身份的限制),::球形smacof(原始和对偶算法)smacof。实现这些方法在度量和非度量方式,包括小学,中学和大专院校的方法,领带处理。

The function for basic SMACOF on symmetric dissimilarity matrices is smacofSym(). For rectangular input matrices (unfolding model) smacofRect() is appropriate and by means of smacofIndDiff() individual difference models (three-way MDS) can be computed.
函数为基本SMACOF对称的相异矩阵的是smacofSym()。对于矩形的输入矩阵(展开模型)smacofRect()的是适当的和由smacofIndDiff()个体差异模型(三通MDS)的,可以计算的装置中。
