AgeBandDecomposition - Age Band Decomposition Method for Tree Ring Standardization
Implements the Age Band Decomposition (ABD) method for
standardizing tree ring width data, while preserving both low
and high frequency variability. Unlike traditional detrending
approaches that can distort long term growth trends, ABD
decomposes ring width series into multiple age classes,
detrends each class separately, and then recombines them to
create standardized chronologies. This approach improves the
detection of growth signals linked to past climatic and
environmental factors, making it particularly valuable for
dendroecological and dendroclimatological studies. The package
provides functions to perform ABD-based standardization, to
compare results with other common methods (e.g., BAI, C method,
RCS), and facilitates the interpretation of growth patterns
driven by environmental variability.
