Figure 4From: Influence of microarrays experiments missing values on the stability of gene groups by hierarchical clusteringComparison of real and kNN predicted values distribution. Histograms of the real values of the OS (1/7) (black bars) and the predicted values using kNN method with k opt = 14 (grey bars) are shown. The values are shown in absolute value. All the values superior to 1.0 (respectively inferior to 0.1) have been pooled in the '> 1.0' group (respectively '< 0.1').Back to article page
