Follow-up Comment #2:

Not seeing this error anymore on Octave 6.4.0 with statistics v.1.4.2.

run from terminal with --eval same way as comment #0, i get:

assuming that the code producing the divide by zero has changed since 2018 and
is no longer an issue, closing the report.  Someone can reopen if I'm
