  2. Rank–size distribution - Wikipedia

    en.wikipedia.org/wiki/Ranksize_distribution

    Ranksize distribution is the distribution of size by rank, in decreasing order of size. For example, if a data set consists of items of sizes 5, 100, 5, and 8, the rank-size distribution is 100, 8, 5, 5 (ranks 1 through 4). This is also known as the rank–frequency distribution, when the source data are from a frequency distribution. These ...
