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 ...

The log-dynamic brain: how skewed distributions affect network operations

At many physiological and anatomical levels in the brain, the distribution of numerous parameters is strongly skewed with a heavy tail and typically follows a lognormal distribution. The power and ...

On Fitting the Truncated Lognormal Distribution to Species-Abundance Data Using Maximum Likelihood Estimation

The truncated lognormal distribution can be used to graduate certain species-abundance data, provided that estimates of the location and scale parameters are obtained. A computer program has been ...
