GSH: Gene Shaving

Parameter Information


Sample Selection

The sample selection option indicates whether to cluster genes or experiments.

Number of Clusters

This integer value indicates the number of clusters to produce. Note that in the GSH algorithm the clusters do not necessarily represent disjoint sets. Some elements may be represented in more than one cluster while other elements may not be represented at all.

Number of Permuted Matrices

This integer value indicates the number of permuted matrices used to generate an average R2 (measure of cluster variance) used to generate the gap statistic.

Number of Permutations/Matrix

This integer value represents the number of alterations to each permuted matrix produced to generate the gap statistic.

Hierarchical Clustering

This check box selects whether to perform hierarchical clustering on the elements in each cluster created.
