objective
returns the “distance” of a
dataset from a particular
Davies distribution as measured by the sums of the squares of the
differences between observed (dataset
and
expected (expected.value()
) values.
objective.approx()
uses expected.approx()
rather than
expected()
to calculate expectations, as per equation 6.
