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.
