可信实验白皮书系列07:高阶实验工具
本文系《可信实验白皮书》系列的第七篇文章。上一篇我们重点介绍了观察性研究,内容主要包括合成控制法、匹配方法、Causal Impact等几个方面。针对单次实验功效不足、假阳性、策略调优等实验中面临的问题,本篇我们来介绍几个高阶实验工具,重点解读了统合分析、多重比较,同时还有一些拓展与展望。
When the RMS Titanic hit an iceberg on 15 April 1912, she set off flares
and her wireless operator sent out a distress call. The RMS Carpathia
responded, but by the time she arrived, the Titanic had already sunk: only
those who had made it to the lifeboats could be saved. Some 1,500 people
died.
Another ship was closer and could potentially have responded faster—perhaps
even fast enough that more lives could have been saved. Yet despite seeing
the flares, she did nothing.
The post Lessons from the Titanic: when you don’t respond to a crisis appeared first on Security Boulevard.
