Usage information is included in the file type 'help plfit' at the Goodness-of-fit based approach to estimating the lower cutoff for the scaling
This function implements both the discrete and continuous maximum likelihoodĮstimators for fitting the power-law distribution to data, along with the randht.m (Matlab, by Aaron Clauset) randht.py (Python, by Joel Ornstein) Usage information is included in the file type 'help randht' at the Matlab One of the five distributions discussed in the article (power law,Įxponential, log-normal, stretched exponential, and power law with cutoff). This function generates continuous values randomly distributed according to Clauset, Power-law distributions in binned empirical data.
