Figure 13.10 Updated Failure Time
When power switch and stripped gear are the only causes of failure, the estimated time for 10% of the
failures increases approximately 31%.
Change the Scale
In the initial Compare Distributions report, the probability and time axes are linear. But suppose that you
want to see distribution estimates on a Fréchet scale. 1
1. Follow step 1 through step 5 in “Example of Life Distribution Analysis” on page 209.
2. In the Compare Distributions report, select Fréchet in the Scale column.
3. Select Interval Type > Pointwise on the red triangle menu.
1. Using different scales is sometimes referred to as drawing the distribution on different types of “probability
paper”.
