Normal diameter (d<sub>n</sub>), a subjective variable-height measure applied to bald cypress (<i>Taxodium distichum</i> (L.) Rich.) in place of diameter at breast height (dbh), was found to be inferior to five different fixed-height diameter measurement points in terms of predicting total volume. Diameter measured at 10 ft (3.0 m) above the ground, termed d<sub>10</sub> is recommended as a better diameter measurement point for bald cypress. A number of "goodness-of-fit" statistics were employed to evaluate alternative functions for predicting volume and taper. Two statistics, bias and sum of squared relative residuals, provided the best discrimination between functions.17: 250-259]]>https://www.srs.fs.usda.gov/pubs/ja/ja_parresol006.pdf227 KBhttps://www.fs.usda.gov/treesearch/pubs/139213920Can.
