I am reading the first vignette of the powerRlaw R package.
It uses the
moby dataset, which is an array of word frequency. Each element is a word, and the value if the frequency of that word in the Moby Dick novel.
At page 5 there is a plot of the CDF for this dataset:
There is a similar plot in the article
Newman, M. E. J. (2005). Power laws, Pareto distributions and Zipf’s law. Contemporary Physics, 46(5), 323–351. https://doi.org/10.1080/00107510500052444
at page 6:
Now Wikipedia says that CDF are increasing functions, starts at 0 and end up at 1.
How can this CDF be decreasing?
