Identifying and Assessing Interesting Subgroups in a Heterogeneous Population

(a) Each simulation contributes a single gray line. The solid black line is the average of 50 simulations, and dashed line is the expected histogram-count vector from . (b) shows singular values from the singular value decomposition (SVD) of , and the dots in (c) and (d) are the components of the singular vectors generated by the SVD, and the solid lines are robust smoothing curves.
