[Octave-bug-tracker] [bug #49961] sign_test() returns incorrect p-value

[Kai Torben Ohlhus]

Follow-up Comment #4, bug #49961 (project octave):

Regarding comment #2: If those functions are going to be dropped, why aren't
they deprecated right now? Maybe one can add a pointer to use the statistics
package.

Regarding comment #3: That makes a blind copy&past to core less desirable, if
the code contains errors. I tried some the tests from the Matlab documentation
([1] in comment #1) but those examples are working. Unless Octave has a Matlab
compatible rng-function (bug #42557) those tests are ugly "hand-writing" of
many numbers.

I suggest to first fix the issues in `signtest` from the statistics package
and then copy&paste the code to a deprecated octave core function
`sign_test`.

Maybe Arno Onken as package maintainer has more insight into that issue.
