Capacitor Example

This example uses Capacitor ALT.jmp 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.

1. Select Help > Sample Data Library and open Reliability/Capacitor ALT.jmp.

2. Select Analyze > Reliability and Survival > Fit Life by X.

3. Select Hours and click Y, Time to Event.

4. Select Temperature and click X.

5. Select Censor and click Censor.

6. Leave the Censor Code as 1.

7. Select Freq as Freq.

8. Keep Arrhenius Celsius as the relationship, and keep the Nested Model Tests option selected.

9. Select Weibull as the distribution.

10. Keep Wald as the confidence interval method.
