The empirical distribution is a distribution where the information is stored in an EmpiricalDistribution, consisting of pairs of values and cumulative probabilities.
Note that interpolated is false for the EmpiricalDistribution to be used in this class, so the function in essence behaves as a discrete distribution, albeit with double values as the outcome. The probability density function returns the equivalent of the discrete distribution function; of course the real probability density function from the viewpoint of a continuous distribution does not exist.
