Draw samples from a log-normal distribution with specified mean, standard deviation, and array shape. Note that the mean and standard deviation are not the values for the distribution itself, but of the underlying normal distribution it is derived from.

Parameters:	mean : float Mean value of the underlying normal distribution sigma : float, > 0. Standard deviation of the underlying normal distribution size : int o 登录查看完整内容 ← → Copyright©2021 w3cschool编程狮|闽ICP备15016281号-3|闽公网安备35020302033924号 违法和不良信息举报电话：173-0602-2364|举报邮箱：jubao@eeedong.com 意见反馈 X 意见反馈： 联系方式： 提交 查看完整版笔记 保存 关闭 违规举报 X 广告等垃圾信息 不友善内容 违反法律法规的内容 不宜公开讨论的政治内容 其他 提交
