Comparison of 1D Density Estimators
-----------------------------------
Figure 6.8

A comparison of different density estimation methods for two simulated
one-dimensional data sets (same as in figure 6.5). Density estimators are
Bayesian blocks (Section 5.7.2), KDE (Section 6.1.1), and a Gaussian mixture
model. In the latter, the optimal number of Gaussian components is chosen using
the BIC (eq. 5.35). In the top panel, GMM solution has three components but one
of the components has a very large width and effectively acts as a nearly flat
background.
