Power Lognormal Analysis

Plots for Power Lognormal Distribution The following plots were generated for a power lognormal 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 100 (i.e., p is asymptotically increasing).

  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 12.01 and the estimate of the scale parameter is 212.92.

  4. Fine tuning the estimate of p (from 50 to 100) has minimal impact on the PPCC value.
