# package for calculating exponent of power law distribution

There are some packages to fitting power law to empirical date in "R", "matlab", "python" Here with maximum likelihood method As it said here. Does it exist similar package in Mathematica?

Fitting is done with EstimatedDistribution or FindDistributionParameters. You want to fit a ParetoDistribution for continuous data or a ZipfDistribution for discrete data.
• @jackcilba You need ParetoDistribtion or ZipfDistribution, but not PowerDistribution, to do what is described in the paper you linked. To choose a fitting method, read the documentation of EstimatedDistribution that I already linked, especially the ParameterEstimator option. Be sure to check under "Details" when reading ay documentation page. – Szabolcs Jun 13 '16 at 12:43
