The BIC curves for the model-based clustering of microarray data including heat response genes. (A) BIC curve for model-based clustering of gene expression data at 37°C, (B) BIC curve for model-based clustering of gene expression data at 48°C. The numerical values of BIC in each model are shown at additional file 4. The model is divided according to the covariance matrix equation form. EII: spherical, equal volume; VII: spherical, unequal volume; EEI: diagonal, equal volume and shape; VEI: diagonal, varying volume, equal shape; EVI: diagonal, equal volume, varying shape; VVI: diagonal, varying volume and shape; EEE: ellipsoidal, equal volume, shape, and orientation; EEV: ellipsoidal, equal volume and equal shape; VEV: ellipsoidal, equal shape; VVV: ellipsoidal, varying volume, shape, and orientation.
