------- Additional comments from [EMAIL PROTECTED] Mon Nov 24 11:21:03 +0000 2008 ------- according to Wikipedia ( http://en.wikipedia.org/wiki/T-distribution ) and to the GNU Scientific Library ( http://www.network-theory.co.uk/docs/gslref/Thetdistribution.html ), the inverse value for a Student's T-distribution, given in Calc by the function TINV, should return something around 1.6 for a percentage of 5% with 200 degrees of freedom. But in Calc the value is a bit higher, it is around 1.9. To reproduce the bug just type in a Calc cell: =TINV(0.05;200) the result should be 1.65 while it is 1.97 why don't you use the GSL for implementing it?
