WebApr 26, 2024 · The data points for the normal distribution don’t follow the center line. However, the data points do follow the line very closely for both the lognormal and the three-parameter Weibull distributions. The gamma distribution doesn’t follow the center line quite as well as the other two, and its p-value is lower. WebJan 8, 2015 · $\begingroup$ @Lourenco I looked at the Cullen and Fey graph. The blue point denotes our sample. You see that the point is close to the lines of the Weibull, Lognormal and Gamma (which is between Weibull and Gamma). After fitting each of those distributions, I compared the goodness-of-fit statistics using the function gofstat and the …
