Next compare the distributions of the positive and negative examples over a few features.
Good questions to ask yourself at this point are:
* Do these distributions make sense?
+ Yes. You've normalized the input and these are mostly concentrated in the +/- 2 range.
* Can you see the difference between the ditributions?
+ Yes the positive examples contain a much higher rate of extreme values.
