This article offers an instructive example of the usefulness of scatter diagrams and of logit regression in decision making. On the morning of 28 January 1986 a US space shuttle named ‘Challenger’ exploded soon after take-off killing all seven crew members who were on board. The launch went ahead on a very cold morning despite attempts by a group of engineers to halt it. They argued that it was unsafe to proceed given the likelihood of malfunctions occurring when the temperature was below freezing. They failed to convince the decision makers involved of any strong connection between temperature at launch and the malfunction of a particular crucial part. This articles discusses how the engineers’ proper use of scatter diagrams and/or logit regression would likely have supported a convincing case to delay the launch of the shuttle.

挑战者号航天飞机灾难：使用散点图和 Logit 回归分析二进制数据的案例研究

本文提供了一个关于散点图和 logit 回归在决策中的有用性的有益示例。1986 年 1 月 28 日上午，一架名为“挑战者”的美国航天飞机在起飞后不久爆炸，机上七名机组人员全部遇难。尽管一群工程师试图阻止发射，发射还是在一个非常寒冷的早晨继续进行。他们争辩说，考虑到温度低于冰点时发生故障的可能性，继续进行是不安全的。他们未能让决策者相信发射时的温度与特定关键部件的故障之间存在任何密切联系。这篇文章讨论了工程师如何正确使用散点图和/或 logit 回归可能会支持一个令人信服的案例来推迟航天飞机的发射.
