suggestion for plot

Might I suggest whoever made the nice plot of the pdfs to add a curve for a value of k less than one to the plot, so we can see it diverge at 0? Otherwise people may think the value at the mode is always finite. Btyner 19:29, 11 May 2006 (UTC)[reply]

I think their is something wrong with the expression of the equation

like $1-k/2\,$ does that mean $1-{\frac {k}{2}}or{\frac {1-k}{2}}orneither?$ —The preceding unsigned comment was added by Tikai (talk • contribs) 15:14, 11 May 2007 (UTC).[reply]

Order of operations states that

1-k/2

is equivalent to

1-{\frac {k}{2}}

And the variance looks wrong too. I believe the variance approaches $1/2$ as $k$ goes to infinity Shabbychef (talk) 22:16, 13 March 2014 (UTC) Oh, wait, my bad, the $\mu$ refers to the mean of the chi, not the means of the normals. This looks fine. Shabbychef (talk) 22:18, 13 March 2014 (UTC)[reply]

Does not chi-distribution have only 1 parameter? So the whole use of <math>\chi(x)<\math> is confusing Кирилл С1 (talk) 20:37, 5 December 2019 (UTC)[reply]
