Abstract : |
Recently, I became interested in a current debate over whether le size distributions are best modelled by a power law distribution or a a lognormal distribution. In trying to learn enough about these distributions to settle the question, I found a rich and long history, spanning many elds. Indeed, several recently proposed models from the computer science community have antecedents in work from decades ago. Here, I brie y survey some of this history, focusing on underlying generative models that lead to these distributions. One nding is that lognormal and power law distributions connect quite naturally, and hence it is not surprising that lognormal distributions have arisen as a possible alternative to power law distributions across many elds. 1, |
