Quantile
Quantile is an algorithm to analyze the distribution of observations. Quantiles are the values that divide the distribution so that a given portion of observations is below the quantile.
Details
Given a set X of p features and the quantile orders , the problem is to compute that meets the following conditions:
In the equations above:
are observations of a random variable that represents the i-th feature
P is the probability measure
