Power Normal Analysis

Plots for Power Normal Distribution

The following plots were generated for a power normal 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 p is 0.05.

2. At the this value of the shape parameter, the PPCC value is 0.988.

3. At the optimal value of the shape parameter, the estimate of the location parameter is 19.0 and the estimate of the scale parameter is 2.4.

4. Fine tuning the estimate of p (from 1 to 0.05) results in a slight improvement of the the computed PPCC value (from 0.980 to 0.988).
