Minitab displays information about the distribution and the intercept and slope of the accelerated life test model. Minitab also displays the assumed value of the shape or scale parameter as follows:

For the capacitor data, Minitab calculates sample sizes assuming an exponential distribution and Arrhenius model with an intercept of -8 and a slope of 0.5. The model equation is:

Log failure time = -8 + 0.5*[11604.83/Temp + 273.16] + ep
