I can't figure out why the \mu is rendering as Roman, rather than italic in this article. Compare to, say, Variance, but there it renders as PNG rather than HTML. And I don't think logging in with special preferences is a solution. — DIV (128.250.204.118 06:04, 18 March 2007 (UTC))

I agree that an italic mu would look better. I wish I knew how to make that appear. Steve8675309 00:29, 20 March 2007 (UTC)
This can be solved by placing \,\! at the end of each formula, as specified at MetaWikiPedia:Help:Formula#Forced_PNG_rendering. --128.250.5.248 (talk) 04:56, 12 August 2009 (UTC)

I think this description of the noncentral t-distribution is incomplete and overly confusing. A scale parameter is generally included and the density can be written much more succinctly. Jurgen (talk) 20:06, 4 May 2010 (UTC)

I am puzzled by the representation of the first form of the CDF. It specifies that when (x < 0) the recursive part of the function---~F()---operates on the reversed sign of x: but ~F() is utterly insensitive to the sign of x, since x only appears in squared terms (i.e. in y). So why bother to assert that the sign of x changes? mu changes sign, yes, but not x. Lexy-lou (talk) 16:14, 20 April 2014 (UTC)
