不知道这个东西是不是只会用这一次,反正搞清楚了,就留下来吧。

在概率论中,对数正态分布是一种连续概率分布,其随机变量的对数服从正态分布。

wiki原话:
A log-normal process is the statistical realization of the multiplicative product of many independent random variables, each of which is positive. This is justified by considering the central limit theorem in the log domain. The log-normal distribution is the maximum entropy probability distribution for a random variate X for which the mean and variance of ln(X</
