摘要
smacof包在R中提供了多维缩放(MDS)技术的全面实现。自从第一次发布(De Leeuw and maair 2009b)以来，包的功能得到了增强，并添加了一些额外的方法、特性和实用程序。主要的更新包括完全重新实现多维展开，允许单调的不相似转换，包括行条件展开、循环展开和外部展开。此外，根据外部变量的最优缩放对约束MDS实现进行了扩展。进一步增加的包包括各种工具和功能，用于拟合优度评估、一维缩放、重力MDS、非对称MDS、Procrustes和MDS双标图。所有这些新的包功能都使用各种实际应用程序进行了说明。
More on Multidimensional Scaling and Unfolding in R: smacof Version 2
The smacof package offers a comprehensive implementation of multidimensional scaling (MDS) techniques in R . Since its first publication (De Leeuw and Mair 2009b) the functionality of the package has been enhanced, and several additional methods, features and utilities were added. Major updates include a complete re-implementation of multidimensional unfolding allowing for monotone dissimilarity transformations, including row-conditional, circular, and external unfolding. Additionally, the constrained MDS implementation was extended in terms of optimal scaling of the external variables. Further package additions include various tools and functions for goodness-of-fit assessment, unidimensional scaling, gravity MDS, asymmetric MDS, Procrustes, and MDS biplots. All these new package functionalities are illustrated using a variety of real-life applications.
