(2023)\n<doi:10.1080/02827581.2023.2243821> and the correction\n<doi:10.1080/02827581.2024.2358467>. Provides functions to\npredict stem diameter along the bole, bark thickness, and stem\nvolume by numerical integration of the taper curve, and to\ninvert these relationships (e.g. estimating height and diameter\nat breast height from measured diameters).",
