R Dataset / Package boot / hirose
On this Picostat.com 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. Try to load the hirose data set in R by issuing the following command at the console data("hirose"). This may 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 library("boot") followed by data("hirose"). Perhaps strangley, if R gives you no output after entering a command, it means the command succeeded. If it succeeded you can see the data by typing hirose at the command-line which should display the entire dataset.
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
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.
This data frame contains the following columns:
The data were obtained from
Hirose, H. (1993) Estimation of threshold stress in accelerated life-testing. IEEE Transactions on Reliability, 42, 650–657.
Davison, A.C. and Hinkley, D.V. (1997) Bootstrap Methods and Their Application. Cambridge University Press.
