BL05 Kernel Density

Previous lecture shows how to generate random variable from beta density, and more generally from ANY density.

This lecture shows how GIVEN A GENERATED data set, HOW can we found out/estimate the DENSITY from which the data was generated

Basically, we use Kernel Density Estimators. To get good estimates by this method, it is essential to vary the window size. However this technique is not taught, and not implemented in computer packages.
