The link to the normal-inverse-wishart distribution does not work Helenuh ( talk) 14:51, 28 February 2008 (UTC) reply

This is because it is not yet written. Please go ahead writing it if you are capable :-) — fnielsen ( talk) 11:30, 12 September 2008 (UTC) reply

the parameterspace cannot be correct as it is written here... maybe m>p??? -- Philtime ( talk) 07:16, 3 July 2009 (UTC) reply

I noticed that as well. (should be m>p-1). fixed— 3mta3 ( talk) 18:45, 13 August 2009 (UTC) reply

See Section The parametriztion for p=1 is not correct. In relation to the inverted gamma distribution it should say α=(m+1)/2, β is correct Can anybody verify that?

Looks odd in the title, and is not in the article text. Can someone explain? Tony (talk) 12:45, 20 October 2011 (UTC) reply

There appears to be more than one parametrization for the inverse Wishart (and presumably the Wishart), making known results mutually unintelligible. Is there a mapping somewhere between them all? Shabbychef ( talk) 18:58, 27 February 2013 (UTC) reply

This article currently says the following:

The probability density function of the inverse Wishart is:

${\displaystyle {\frac {\left|{\mathbf {\Psi } }\right|^{\frac {\nu }{2}}}{2^{\frac {\nu p}{2}}\Gamma _{p}({\frac {\nu }{2}})}}\left|\mathbf {X} \right|^{-{\frac {\nu +p+1}{2}}}e^{-{\frac {1}{2}}\operatorname {tr} ({\mathbf {\Psi } }\mathbf {X} ^{-1})}}$

Is this a function of Ψ or of X or what? This article is full of terrible notation and this is an instance. Michael Hardy ( talk) 04:33, 2 May 2018 (UTC) reply

The pdf field in the info box uses a lower-case x (which implies it is a vector) - I went through and changed instances of this elsewhere, but in the info box whenever I try to change it the LaTeX crashes. This is a fairly strange error, I wasn't able to work out a way around it, so I figured I'd just pop a mention of it here.
