WebIn a looser sense, a power-law probability distribution is a distribution whose density function (or mass function in the discrete case) has the form, for large values of , [44] where , and is a slowly varying function, which is any function that satisfies for any positive factor . Vilfredo Pareto originally used this distribution to describe the allocation of wealth among individuals since it seemed to show rather well the way that a larger portion of the wealth of any society is owned by a smaller percentage of the people in that society. He also used it to describe distribution of income. This idea is sometimes expressed more simply as the Pareto principle or the "80-2…
