Title

Simon's generating mechanism : consequences and their correspondence to empirical facts

Abstract

By considering hypothetically the Bradford distribution, as a dynamic system developing in time on principl formally equivalent to that proposed by Siman, it was shown that though the Simon generating mechanism gives rise to certain qualitative features ascribes to data, the resulting distribution function, derived as a steady-state solution of the proposed stochastic process, is too restricted to cope with the variation produced in time. The empirical evidence, combined with the results of goodness-of-fit test, strongly support this fact, showing explicitly that the changes in the shape of the distribution that appear in the course of time, particularly the changes in the low producing tail, reduce excessively the scope of the model marking the limits of its applicability
