I think there should be a definition section in the beginning of the article. Apparently Lomax originally proposed two different distributions. It might also be helpful to mention that the survival function can be expressed as [1] or as [2]. Isheden ( talk) 11:02, 19 October 2012 (UTC)
It also needs to be clarified whether the support includes or excludes zero. Isheden ( talk) 12:49, 19 October 2012 (UTC)
The article says: "The Lomax distribution, also called the
Pareto Type II distribution, . . . ". Using the given internal link, it is seen that the Lomax distribution is identical to the Pareto Type II distribution only when μ=0. Hence it is a simplified Pareto Type II distribution. Should this not be mentioned here?
Be aware that μ in this context is not the same as the more common use of μ as (population) mean or expected value. Asitgoes ( talk) 12:37, 19 October 2012 (UTC)
Some more. In the section "Relation to the Pareto distribution" it is said that: "The Lomax distribution is a Pareto Type I distribution shifted so that its support begins at zero." There is quite some difference between Type I and Type II so that this statement needs explanation. Could someone give that? Asitgoes ( talk) 13:05, 19 October 2012 (UTC)
