Example 10.2: Estimating Parameters from Lognormal Plots

Note: You must specify a value for the shape parameter for a lognormal Q-Q plot with the SIGMA= option or its alias, the SHAPE= option. The plot in Output 10.2.2 displays the most linear point pattern ...

Example 4.6: Fitting a Three-Parameter Lognormal Curve

If you request a lognormal fit with the LOGNORMAL option, a two-parameter lognormal distribution is assumed. This means that the shape parameter and the scale parameter are unknown (unless specified) ...
