The purpose of this package is to tests whether a given
moment of the distribution of a given sample is finite or not. For
heavy-tailed distributions with tail exponent b, only moments of
order smaller than b are finite. Tail exponent and heavy-
tailedness are notoriously difficult to ascertain. But the
finiteness of moments (including fractional moments) can be tested
directly. This package does that following the test suggested by
Trapani (2016)
