摘要
用极大似然估计和KS统计量拟合幂律分布α指数和xmin值的研究,是复杂网络中幂律分布拟合的新进展。运用上述方法对广州软件产业、佛山陶瓷产业和中国家电产业竞争关系网络以及百度百科词条生产网络的分布进行研究,并与用最小二乘方法的估计进行比较,得出了一些新结论。
Aaron Clauset et al. used the Maximum Likelihood Estimate Method and Kolmogorov-Smirnov Statistics to fit the Power-Law distributions＇ aand XminValues, which is the latest development in complex network fields. On the basis of the method, several degree distributions of networks, including GuangZhou software industry, FoShan Ceramics industry, Chinese household appliances industry and Baidu Cyclopedia lemmas industry, were studied. The results were compared with the previous ones, Some conclusions are obtained.
