I continue to find probability distributions with infinite means fascinating. Particularly how their averages *don't converge* as you sample more values.
You can even replicate the behavior deterministically with "tan at integers" as a pseudo-RNG. https://t.co/KmfUXpqKLx
我继续发现具有无限均值的概率分布令人着迷。特别是当您采样更多值时，它们的平均值如何*不收敛*。
您甚至可以使用“整数 tan”作为伪 RNG 来确定地复制行为。 https://t.co/KmfUXpqKLx
