Percentiles and survival probabilitiesmain topic
Percentiles and survival probabilitiesWhen doing accelerated life testing, you subject units to levels of an accelerating variable(s) far exceeding normal field conditions to accelerate the failure process. But most likely, the information you ultimately want is, How do the units behave under normal field conditions?
In the Estimate subdialog box, you can ask Minitab to extrapolate information gained from the accelerated situation to the design value, or common field condition.

Sometimes you may want to estimate percentiles, survival probabilities, or cumulative failure probabilities for the accelerating variable(s) levels used in the study: In the Estimate subdialog box, choose, Use predictor values in data (storage only). Because of the potentially large amount of output, Minitab store the results in the worksheet rather than printing them in the Session window. |
