1. A method of estimating a measure of randomness of a function of at least one representative value of at least one random variable, a plurality of individual data values of which are randomly distributed, the method comprising:

  • a step of obtaining the at least one random variable;

    a step of determining the at least one representative value of the obtained at least one random variable, using a computer;

    a step of determining a statistic of the obtained at least one random variable, using the computer;

    a step of determining a gradient of the function with respect to the determined at least one representative value, using the computer; and

    a step of estimating the measure of randomness of the function, wherein the step of estimating includes transforming by the computer the obtained statistic of the at least one random variable into a statistic of the function, using the determined gradient.
