Popis:	Fractal properties of the Pareto probability distribution are used to generalize “the 20/80 law.” The 20/80 law is a heuristic law that has evolved over the years into the following rule of thumb for many populations: 20 percent of the population accounts for 80 percent of the total value. The generalp100/q100 law in probabilistic form is defined withq as a function ofp, wherep is the population proportion andq is the proportion of total value. Using the Pareto distribution, thep100/q100 law in fractal form is derived with the parameterq being a fractal, whereq unexpectedly possesses the scale invariance property. The 20/80 law is a special case of thep100/q100 law in fractal form.
