Figure 6From: Measuring similarities between gene expression profiles through new data transformationsGap statistic results on the 39 yeast sporulation genes. The x-axis represents the number of clusters and the y-axis represents the gap statistics over different number of clusters. In each sub-figure, the x-axis value associated with the largest gap statistic is the optimal selection of the number of clusters under the used similarity measure. From the shown gap curves, only TransChisq provides a correct estimate on the true number of clusters, 7.Back to article page
