Distribution class

Distribution represents a frequency distribution of double-valued sample points.

It contains the size of the population of sample points plus additional optional information: * the arithmetic mean of the samples * the minimum and maximum of the samples * the sum-squared-deviation of the samples, used to compute variance * a histogram of the values of the sample points
