ABS: Rousseau, LOTKA: A program to fit a power law distribution to observed frequency data

[Isidro F. Aguillo]

Dear all:

We recently published new papers in the ejournal Cybermetrics, including
a innovative one that includes a software program. It is not usual in
paper format but it is an important added value of electronic sources.
We will very happy to publish similar contributions.

Abstract
LOTKA, a computer program for fitting a power law distribution such as
Lotka’s is presented. It basically follows Nicholl’s methodology : using
a maximum likelihood approach to estimate parameters, and a
Kolmogorov-Smirnov test for goodness-of-fit. When input data are
converted (from rank-frequency to size-frequency) this program can also
be used to test Zipf’s law.
