Gamma Analysis

Plots for Gamma Distribution

The following plots were generated for a gamma distribution.

Conclusions

We can make the following conclusions from these plots.

1. The optimal value, in the sense of having the most linear probability plot, of the shape parameter is 11.8.

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

3. At the optimal value of the shape parameter, the estimate of the location parameter is 5.19 and the estimate of the scale parameter is 2.17.

4. Fine tuning the estimate of (from 12 to 11.8) has some impact on the PPCC value (from 0.978 to 0.987).
