Fig. 6From: Statistical analysis of high-dimensional biomedical data: a gentle introduction to analytical goals, common approaches and challengesPrincipal component analysis plot depicting 62 lymphoma samples represented by their first and second principal component calculated from gene expression profiles comprising expression levels of 4026 genes on each lymphoma sample. The samples have been annotated in the plot according to pathologic subtype: 11 B-cell chronic lymphocytic leukemia (B-CLL; blue squares), 9 follicular lymphoma (FL; black triangles), and 42 diffuse large B-cell lymphoma (DLCL; red dots).
