- property NSSDNResult.oscillation: NDArray[float64][source]#
(r,)the oscillatory part of the emission, \(\hat y_t - B_t\).Equal to
components.sum(axis=1). A fit whose oscillation has negligible variance has put the series into the trend head, which short schedules do; the ratio of its variance to that ofobservedis the quickest check that the components carry anything.
