摘要
Zipf-Mandelbrot律S∝(r+ρ)-α是对Zipf律的改进,但是参数ρ的含义一直不清楚.本文直接生成符合Zipf-Mandelbrot律的随机数据序列,通过对比指出Zipf-Mandelbrot律是由系统规模约束造成的,参数ρ反映了数据的饱和效应.
The Zipf-Mandelbrot law S∝(r+ρ)-α is an improvement of Zipfian law,but little is known about the implication of parameter ρ.This paper constructs a random data series following the Zipf-Mandelbrot law.It was found that Zipf-Mandelbrot law results from limited scale of the real system,parameter r reflects saturation effect of sampled data.
