R Dataset / Package boot / hirose

On this R-data statistics page, you will find information about the hirose data set which pertains to Failure Time of PET Film. The hirose data set is found in the boot R package. You can load the hirose data set in R by issuing the following command at the console data("hirose"). This will load the data into a variable called hirose. If R says the hirose data set is not found, you can try installing the package by issuing this command install.packages("boot") and then attempt to reload the data with the library() command. If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the hirose R data set. The size of this file is about 464 bytes.

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; 1 means right-censored data.

Source

The data were obtained from

Hirose, H. (1993) Estimation of threshold stress in accelerated life-testing. IEEE Transactions on Reliability, 42, 650–657.
