如何使用Scipy生成特定分布的随机值

Question

I want to generate a random number following a lognormal distribution with Scipy. I understand from the documentation that you can use:

import scipy.stats
R = scipy.stats.lognorm.rvs()

But I want to use specific parameters. I cannot find an example. This is what I want to do:

params = (0.6718101713289113, -3.5861418072007032, 44.598580116376482)
R = scipy.stats.lognorm.rvs(params)

But this does not work. What is the correct syntax?

Answer 1

You only pass one parameter, a tuple, to rvs. You have to unpack the tuple:

R = scipy.stats.lognorm.rvs(*params)
