devicea: Temperature-accelerated life test data

In Auburngrads/SMRD: Statistical Methods For Reliability Data

Description

Hooper and Amster (1990) analyze the temperature-accelerated life test data on an unidentified device. Meeker and Escobar (1998) refer to this device as "Device A". The purpose of the experiment was to determine if "Device A" would meet a failure rate objective through 10,000 hours and 30,000 hours at an operating ambient temperature of 10 degrees celsius. Device samples were tested for up to 5000 hours at four separate temperatures.

Format

A data.frame with 37 rows and 4 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 to the device during testing	Numeric
