Frequency‐rank distributions

Frequency, rank, and frequency‐rank distributions are distinguished and discussion then focuses on frequency‐rank distributions. The key example of frequency‐rank distributions is the so‐called “law of anomalous numbers” which, modeled as a “very mixed” Poisson process and simulated by computer, provides a means of exploring the stability of ranks in sample frequency‐rank distributions. The paper concludes with a critical discussion of the correlation of frequency‐rank distributions and offers a new measure‐the transfer coefficient.
