Editing Mixture model (section)

=== Graphical Methods ===

Tarter and Lock<ref name="tart" /> describe a graphical approach to mixture identification in which a kernel function is applied to an empirical frequency plot so to reduce intra-component variance.  In this way one may more readily identify components having differing means.  While this ''λ''-method does not require prior knowledge of the number or functional form of the components its success does rely on the choice of the kernel parameters which to some extent implicitly embeds assumptions about the component structure.
