Figure 3From: Effect of data normalization on fuzzy clustering of DNA microarray dataBoxplots of sorted membership values for the serum dataset for four different m values. Boxplots of sorted membership values for the serum dataset, for three normalization methods and four values of m ranging from 1.2 to 1.8. The x axis indicates the number of clusters, and the y axis indicates membership value (a) Z-normalization (b) R-normalization (c) Lowess-normalization.Back to article page
