Measuring Preferential attachment by Poisson Pseudo Maximum Likelihood Method

How to measure Preferential attachment?PDF+LS,CDF+LS,PPML Comparisons of PDF+LS,CDF+LS against PPML Conclusion What is Preferential attachment?Preferential attachment is first used by Barabasi and Albert in1999to describe the phenomenon of"the rich get richer"in network science.Currently widely used methods：Probability distribution function，cumulative distribution function。This approach gives consistent estimationregardless of how the data are in fact distributed, i.e.,they do not need to be Poisson at all, nor even count data.
