Capacitor Example

This example uses Capacitor and can be found in the Reliability folder of the sample data. It contains simulated data that gives censored observations for three levels of temperature, for a reliability study. Observations are shown as censored values at temperature levels of 85, 105, and 125 degrees Celsius.
