Fatigue Life Analysis

Plots for Fatigue Life Distribution

The following plots were generated for a Fatigue Life distribution.

Conclusions

We can make the following conclusions from these plots.

1. A reasonable value, in the sense of having the most linear probability plot, of the shape parameter is 0.178.

2. At this value of the shape parameter, the PPCC value is 0.987.

3. At this value of the shape parameter, the estimate of the location parameter is 11.03 and the estimate of the scale parameter is 41.28.

4. Fine tuning the estimate of (from 0.5 to 0.18) improves the PPCC value (from 0.973 to 0.987).
