Within Cluster Resampling
ELAINE BORLAND HOFFMAN: Within Cluster Resampling (Under the direction of Clarice R. Weinberg) Dependence among observations from the same group is known as within-cluster correlation. Typically, distinct clusters are independent, but special methods are required to account for the existence of the within-cluster correlation. Although not accounting for the within-cluster correlation may produc...
متن کاملA Resampling Approach to Cluster Validation
The concept of cluster stability is introduced as a means for assessing the validity of data partitionings found by clustering algorithms. It allows us to explicitly quantify the quality of a clustering solution, without being dependent on external information. The principle of maximizing the cluster stability can be interpreted as choosing the most self-consistent data partitioning. We present...
متن کاملResampling Method For UnsupervisedEstimation Of Cluster
We introduce a method for validation of results obtained by clustering analysis of data. The method is based on resampling the available data. A gure of merit that measures the stability of clustering solutions against resampling is introduced. Clusters which are stable against resam-pling give rise to local maxima of this gure of merit. This is presented rst for a one-dimensional data set, for...
متن کاملWithin-Cluster Resampling for Analysis of Family Data: Ready for Prime-Time?
Hoffman et al. [1] proposed an elegant resampling method for analyzing clustered binary data. The focus of their paper was to perform association tests on clustered binary data using within-cluster-resampling (WCR) method. Follmann et al. [2] extended Hoffman et al.'s procedure more generally with applicability to angular data, combining of p-values, testing of vectors of parameters, and Bayesi...
متن کاملResampling Method for Unsupervised Estimation of Cluster Validity
We introduce a method for validation of results obtained by clustering analysis of data. The method is based on resampling the available data. A figure of merit that measures the stability of clustering solutions against resampling is introduced. Clusters that are stable against resampling give rise to local maxima of this figure of merit. This is presented first for a one-dimensional data set,...
