%description
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, compare results with other common methods (e.g., BAI, C
method, RCS), and facilitate the interpretation of growth patterns under
current and future climate variability.
