Accelerated life tests on electrical insulation in motorettes with censoring times.
motorettes
A data frame with 40 observed times of life tests on electrical insulation in motorettes at four different temperatures (150C, 170c, 190c and 200c). y corresponds to log10 of the failure time (or end of study time, in case of right censored observations), x corresponds to (100/(temperature + 273.2)) and cc is a indicator of censoring (1 if censored, 0 if not).
