Figure 2: Examples of the flowClust B I C , flowClust I C L , flowMerge cluster solutions for forward versus side scatter in a sample of CLL flow cytometry data. (a) The flowClust B I C solution with seven clusters. (b) The flowClust I C L solution with two clusters. (c) The entropy versus number of clusters plot, fit to a two-component piecewise linear regression model. The best fitting model has a changepoint at three clusters. (d) The flowMerge solution corresponding to 𝐾 = 3 clusters provides a better fit to the lymphocyte population than either the flowClust B I C or flowClust I C L solutions and provides a good estimate of the true number of cell populations.
