On the robust estimation of power spectra, coherences, and transfer functions

Chave, Alan D., Thomson, David J., Ander, Mark E.·1987·Journal of Geophysical Research: Solid Earth

Abstract

Robust estimation of power spectra, coherences, and transfer functions is investigated in the context of geophysical data processing. The methods described are frequency‐domain extensions of current techniques from the statistical literature and are applicable in cases where section‐averaging methods would be used with data that are contaminated by local nonstationarity or isolated outliers. The paper begins with a review of robust estimation theory, emphasizing statistical principles and the maximum likelihood or M‐estimators. These are combined with section‐averaging spectral techniques to obtain robust estimates of power spectra, coherences, and transfer functions in an automatic, data‐adaptive fashion. Because robust methods implicitly identify abnormal data, methods for monitoring the statistical behavior of the estimation process using quantile‐quantile plots are also discussed. The results are illustrated using a variety of examples from electromagnetic geophysics.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
