详细信息----------Details----------
The Ford Explorer is a popular sports utility vehicle made in the United States and sold throughout the world. Early in its production concern arose over a potential accident risk associated with tires of the prescribed size when the vehicle was carrying heavy loads, but the risk was thought to be acceptable if a low tire pressure was recommended. The problem was apparently exacerbated by a particular type of Firestone tire that was overly prone to separation, especially in warm temperatures. This type of tire was a common one used on Explorers in model years 1995 and later. By the end of 1999 more than 30 lawsuits had been filed over accidents that were thought to be associated with this problem. U.S. federal data on fatal car accidents were analysed at that time, showing that the odds of a fatal accident being associated with tire failure were three times as great for Explorers as for other sports utility vehicles.
福特Explorer是一款流行的运动型多功能车在美国和世界各地的销售。早在其生产的关注引发潜在事故风险与规定尺寸的轮胎，当车辆搬运重物，但如果轮胎气压低，建议的风险被认为是可以接受的。过于容易分离，特别是在高温环境下的一个特定类型的Firestone轮胎显然是加剧了这个问题。这种类型的轮胎是常见的一种模型1995年和以后的探索者。到1999年底的30多起诉讼被认为与此问题相关的事故，已申请了。当时美国联邦致命的车祸数据进行了分析，表示与轮胎故障发生致命事故的可能性三次伟大的探险家其他运动型多功能车。
Additional data from 1999 and additional variables may be used to further explore the odds ratio. It is of interest to see whether the odds that a fatal accident is tire-related depend on whether the vehicle is a Ford, after accounting for age of the car and number of passengers. Since the Ford tire problem may be due to the load carried, there is some interest in seeing whether the odds associated with a Ford depend on the number of passengers.
从1999年和额外的变量可用于进一步探索的可能性比其他数据。这是看是否取决于是否一宗致命意外的几率是与轮胎有关的车辆是福特，后占的汽车和乘客人数，年龄。由于福特轮胎的问题可能是由于所带负载，看是否与福特的可能性取决于上的乘客人数有一定的兴趣。
