hirose:
Failure Time of PET Film
Description
The hirose data frame has 44 rows and 3 columns.
PET film is used in electrical insulation. In this accelerated life test
the failure times for 44 samples in gas insulated transformers. 4 different
voltage levels were used.
Format
This data frame contains the following columns:
volt-
The voltage (in kV).
time-
The failure or censoring time in hours.
cens-
The censoring indicator;
1 means right-censored data.
Source
The data were obtained from Hirose, H. (1993) Estimation of threshold stress in accelerated life-testing.
