title: How is the bandwith calculated in Weka KernelEstimator class?
body: <p>I am using Weka to calculate the probability for a given dataset. More specifically I am using the <a href="http://weka.sourceforge.net/doc/weka/estimators/KernelEstimator.html" rel="nofollow noreferrer">KernelEstimator</a> class. </p>
  
  <p>For good density estimation results the choice of the bandwith parameter is crucial, but I have not been able to find out how the bandwith parameter is calculated. The kernel function being used is a simple <a href="http://en.wikipedia.org/wiki/Gaussian_kernel" rel="nofollow noreferrer">Gaussian Kernel</a>. Does anyone know how the bandwith parameter is calculated?</p>
