This example uses the Devalt.jmp sample data table, from Meeker and Escobar (1998), and can be found in the Reliability folder of the sample data. It contains time-to-failure data for a device at accelerated operating temperatures. No time-to-failure observation is recorded for the normal operating temperature of 10 degrees Celsius; all other observations are shown as time-to-failure or censored values at accelerated temperature levels of 40, 60, and 80 degrees Celsius.
