Notes
See http://en.wikipedia.org/wiki/Cumulative_distribution_function For more details on the estimation see Ref. [5] in module docstring.
The multivariate CDF for mixed data (continuous and ordered/unordered discrete) is estimated by:
where G() is the product kernel CDF estimator for the continuous and L() for the discrete variables.
Used bandwidth is self.bw.
