Notes
For more details on the estimation see [5], and p.181 in [1].
The multivariate conditional CDF for mixed data (continuous and ordered/unordered discrete) is estimated by:
where G() is the product kernel CDF estimator for the dependent (y) variable(s) and W() is the product kernel CDF estimator for the independent variable(s).
