Figure 3From: CLUSFAVOR 5.0: hierarchical cluster and principal-component analysis of microarray-based transcriptional profilesJack-knife distance functions for HCA minimize bias due to outlier effects. Correlation between expression profiles for genes 1 and 2 drops from (a) 0.83 to (b) -0.37 when expression values for array 7 (outlier) are dropped from the calculation of correlation.Back to article page
