Creating Lognormal Probability Plots

When you request a lognormal probability plot, you must specify the shape parameter for the lognormal distribution (see Table 9.13 for the equation). The value of must be positive, and typical values ...

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 ...
