Issue No.12 - December (1975 vol.24)
A technique is presented that uses both cluster analysis and a Monte Carlo significance test of clusters to discover associations between variables in multidimensional data. The method is applied to an example of a noisy function in three-dimensional space, to a sample from a mixture of three bivariate normal distributions, and to the well-known Fisher's Iris data.
Clustering algorithms, data analysis, multivariate analysis, nonlinear data structures, pattern recognition.
