求大米贴 －－A／B test 面试问题总结

谢谢楼主分享！

谢谢楼主！mark一下

Very helpful! The only comment is at point 10:"Then using a grid of sample size values to calculate beta (the pdf of reject the null when the null is true) using pnorm()", I think beta represents type II error in hypothesis testing. If so, beta should represent the pdf of not rejecting the null hypothesis when the null hypothesis is false. Hope it clarifies.
