Inter cluster variance
WebWard’s minimum variance method: It minimizes the total within-cluster variance. At each step the pair of clusters with minimum between-cluster distance are merged. Note that, at each stage of the clustering process the two clusters, that have the smallest linkage distance, are linked together. WebApr 28, 2004 · Increasingly, researchers are recognizing that there are many situations where the use of a cluster randomized trial may be more appropriate than an individually randomized trial. Similarly, the need for appropriate standards of reporting of cluster trials is more widely acknowledged. In this paper, we describe the results of a survey to inform the …
