probability distribution power law distribution a power-law probability distribution is a probability distribution whose density function (or mass function in the discrete case) has the form p(x) = L(x) . x^{-alpha} where alpha is a parameter >1 and L(x) is a slowly varying function. adapted from wikipedia and wolfram alpha: https://en.wikipedia.org/wiki/Power_law#Power-law_probability_distributions last accessed: 2015-11-03 http://docs.scipy.org/doc/scipy/reference/generated/scipy.stats.powerlaw.html#scipy.stats.powerlaw https://cran.r-project.org/web/packages/poweRlaw/index.html ready for release
