Java Applet
This applet allows for the calculation of the decision boundary given a
three dimensional feature vector. Specifically, by stipulating the
variables such as the priors, and the conditional likelihoods of each
feature with respect to each class, the changing decision boundary will
be displayed.

How to use the Applet
Use the scroll bars to input the values of P and Q where they are the
probabilities of X=1 given class 1 or class 2 respectively.
Furthermore, the Pw1 and Pw2 are the respected priors.
once complete, press the compute button and the decision plane will be
displayed given that it exists and is not infinity.
