Talk:Chi distribution

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)

I think their is something wrong with the expression of the equation
like$$1-k/2\,$$ does that mean $$1-\frac{k}{2} or \frac{1-k}{2} or neither?$$ —The preceding unsigned comment was added by Tikai (talk • contribs) 15:14, 11 May 2007 (UTC).


 * Order of operations states that $$1-k/2$$ is equivalent to $$1-\frac{k}{2}$$. Svyatoslav (talk) 21:29, 10 December 2012 (UTC)

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)
