The BIC scores in model-based clustering for the Yeast cell cycle data using 71 B-spline bases in order to determine the number of clusters. Model VVI with six clusters is selected, where “VVI” represents that diagonal, varying volume, and varying shape covariance matrix is used in model-based clustering. 1=EII: spherical, equal volume, 2=VII: spherical, unequal volume, 3=EEI: diagonal, equal volume, equal shape 4=VVI: diagonal, varying volume, varying shape, 5=EEE: ellipsoidal, equal volume, shape, and orientation 6=VVV: ellipsoidal, varying volume, shape, and orientation.
