_______________________________________________________
Details:
The documentation for both function states that (about lines 44-45)
If @var{h} is 0 the null hypothesis is accepted, if it is 1 the null
hypothesis is rejected.
But this is incorrect, the null hypothesis is never accepted. It would be
factually correct to instead state
If @var{h} is 1 the null hypothesis is rejected, if is 1 the null hypothesis
can not be accepted.
Which has a completely different meaning (we can never accept the null
hypothesis). It is possible other stat related function also make that
mistake, I did not check all of them out.
