Biomarkers for pancreatic cancer: Recent achievements in proteomics and genomics through classical and multivariate statistical methods

Figure 1 Example of a dendrogram built using Ward’s linkage method and euclidean distances. Data refer to samples from two pancreatic cancer cell lines treated or not with trichostatin A.

Figure 2 Example of the graphical representation of the results from Ranking-PCA. Trend of Ind₂vs the increasing number of variables added to the model (A); trend of the distance between the two class centroids vs the number of variables added to the model (B). Variables on the X-axis are reported in the order in which they are included in the model. Both calibration and cross-validation results are reported.
