zelencap: Glass Capacitor Accelerated Life Test

Description Format Source See Also

Description

Zelen describes an accelerated life test performed on glass capacitors at higher than usual levels of temperature and voltage. The data were obtained from a factorial experiment in which eight capacitors were tested at each combination of temperature and voltage. For each combination, the test was terminated after the fourth failure was observed, yielding failure (Type II) censored data.

Format

A data.frame with 40 rows and 5 variables:

[, 1] hours Accumulated time at event Numeric
[, 2] event Event observed at hours (failure/right-censored) Categoric
[, 3] count Number of events observed at hours Numeric
[, 4] celsius Temperature applied Numeric
[, 5] volts Electrical power applied Numeric
