R Documentation
O-ring failures against temperature for shuttle launches
Description
This dataset records the occurence of failures in the O-rings of space
shuttles against the temperature at the time of the launches. One (1) stands
for a failure and zero for a success.
Usage
data(challenger)
Format
A data frame with 23 observations on the following 2 variables.
oring
Occurence or not of an O-ring failure
temp
Temperature at the time of the launch
Details
In 1986, the space shuttle Challenger exploded during take off, killing
the seven astronauts aboard. The explosion was the result of an O-ring failure, a splitting
of a ring of rubber that seals the parts of the ship together. The accident was believed
to be caused by the unusually cold weather (31 degrees F or 0 degrees C) at the time of launch, as
there is reason to believe that the O-ring failure probabilities increase as temperature
decreases.
