Beta Prime and F

[edit]

The comment about Beta Prime and F appears to be incorrect. Although it makes sense that these are related the statement that if b is beta prime, then b*alpha/beta is F can't make sense, since if alpha = beta then you just get b and F distribution is not invariant when you multiply d1 and d2 by constants. —Preceding unsigned comment added by 83.244.153.18 (talk) 11:31, 7 April 2010 (UTC)[reply]

Cumulative distribution function and excess kurtosis

[edit]

Dear main authors: as you probably know, the beta-prime distribution is the same as the F-distribution, if one replaces in the latter: , , . That means that part of the text in the F-distribution-article can be copied and pasted into this article. That's what I did for the CDF and the kurtosis.

should be flipped to get

If has an F-distribution, then , or equivalently, .

Alternative parameterization does not match parameters from sidebox

[edit]

The sidebox of the article states that the mean and variance of the distributions are

and

However, solving the system of equations for and shows the alternate parameterization should be

and

So the given solution in the text is incorrect — Preceding unsigned comment added by 198.208.46.92 (talk) 23:57, 20 June 2022 (UTC)[reply]
