[Gretl-users] Re: Paired T-Test Kruskal-Wallis test C API

Hello
I was wondering if the Gretl API offers a paired t-test or the Kruskal–Wallis test for
more than two variables.
Hi, about the Kruskal-Wallis test: AFAIK the contributed package
"KruskalWallis" is the only offering, and hence not in C, but in hansl.
But in there the KruskalWallis2 function appears to support several
variables.
(@Jack, BTW: I guess the issue is practically moot now, but I think the
package requirement would have to be 1.9.12 instead of 1.9.4.)
The paired t-test is built into the GUI in the test statistic
calculator, so there's a C backend "somehow". But do you already know
how to do a simple mean test through the C API? Then I guess the
recommendation is to form the difference of the two (paired) series and
proceed as usual.
cheers
