This example is a continuation of "Creating Lognormal Probability Plots". Figure 9.4 shows that a lognormal distribution with shape parameter is a good fit for the distribution of DIAMETER in the data ...

In this article we construct an upper prediction limit for the arithmetic mean of a future sample from a lognormal distribution. First, we present three approximate distributions for the total of the ...

The control limits can be replaced with the corresponding percentiles from a fitted lognormal distribution. The equation for the lognormal density function is where denotes the shape parameter and ...

This is a preview. Log in through your library . Abstract 1. Of the many model for species-abundance distributions (SADs), the lognormal has been the most popular and as been put forward as an ...

In order to introduce left and right truncated versions of the modified lognormal with a power-law distribution, we derive its probability density function, its distribution function, its average ...
