logarithmic

The logarithmic distribution is a discrete distribution bounded by [1,…]. theta is related to the sample size and the mean.

The logarithmic distribution is used to describe the diversity of a sample, that is, how many of a given type of thing are contained in a sample of things. For instance, this distribution has been used to describe the number of individuals of a given species in a sampling of mosquitoes, or the number of parts of a given type in a sampling of inventory. (see Johnson et.al.1).
