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.
Usage
hirose
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; 1means right-censored data.
