We present R and C implementations for metric (ratio) and non-metric (ordinal) versions of Elastic MDS, the multidimensional scaling technique proposed by McGee (1966). The R and C versions are compared for speed, with the C version anywhere from 15 to 100 times as fast as the R version.
翻译:本文提供了McGee(1966)提出的多维标度技术——弹性多维标度法的度量(比率)与非度量(序数)版本的R语言与C语言实现。通过对比R语言与C语言版本的速度性能,C语言版本的运行速度可达R语言版本的15至100倍。
