Uclust: Clustering and Classification Inference for HDLSS Data with U-Statistics

Package may be downloaded on CRAN

Clustering and classification inference for high dimension low sample size data with U-statistics. The package contains implementations of nonparametric statistical tests for sample homogeneity, group separation, clustering, and classification of multivariate data. The methods have high statistical power and are tailored for data in which the dimension L is much larger than sample size n. 

The package contains functions for nonparametric tests:

• Bn test for group separation with 2 or 3 predefined groups
• Overall group homogeneity testing
• Clustering of a sample into the best two our three significant subgroups
• Hierarchical clustering considering only significant subgroups
• Significant classification of a new observation into one of two predefined groups

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
