Details:

The test for `ttest` in nan 3.5.0 with Octave 6.0.92 fails with the following
error:

>> test ttest
***** test
 x = 8:0.1:12;
 [h, pval, ci] = ttest (x, 10);
 assert (h, 0)
 assert (pval, 1, 10*eps)
 assert (ci, [9.6219 10.3781], 1E-5)
 [h, pval, ci0] = ttest (x, 0);
 assert (h, 1)
 assert (pval, 0)
 assert (ci0, ci, 2e-15)
 [h, pval, ci] = ttest (x, 10, "tail", "right", "dim", 2, "alpha", 0.05);
 assert (h, 0)
 assert (pval, 0.5, 10*eps)
 assert (ci, [9.68498 Inf], 1E-5)
!!!!! test failed
'betainv' undefined near line 49, column 49

The 'betainv' function belongs to the statistics package from Octave
Forge which you have installed but not loaded.  To load the package, run
'pkg load statistics' from the Octave prompt.

Please read <https://www.octave.org/missing.html> to learn how you can
contribute missing functionality.


`betainv` has been moved from Octave core to the "statistics" package.
The "nan" package should probably add a dependency on "statistics" so that it
is loaded automatically.

CC'ing Alois Schlögl as the package manager.
