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.
