2, especially between the truncatedpower-law and the lognormal distribution. We use the loglikelihood ratio tofurther compare these two candidate distributions. The loglikelihood ratiois positive if the data is more likely in the power-law distribution, andnegative if the data is more likely in ...
A power-law distribution in empirical data is a striking feature that has attracted considerable attention19. The power-law can relate microcosmic theory to observed macroscopic phenomena. Although power-law distri- butions have been reported in areas ranging from ecology and molecular biology to ...
当然,复杂系统也不能点石为金,将幂律分布数据变成正态分布数据、而是用整个一套完全不同的思想和方法来看变量的分布和变量之间的关系。(参见A. Clauset, C.R. Shalizi, and M.E.J. Newman, "Power-law distributions in empirical data"SIAM Review, 2009)。

A quantity x is said to obey a power law is it is drawn from a probability distribution given by p(x)∝x−α where α is a constant parameter known as exponent. In this chapter we will look at ways to determine whether or not a certain set of values follow a power law. We will...
