Table 27-65B — Regression equations for estimating above-stump green cubic-foot vol- 

 ume of the whole tree and its components for scarlet oak trees 6 to 20 inches in dbhfrom 

 natural stands in the Southeast, using dbh and total height as independent variables 

 (Clark et al. 1980b)— Continued 



•Y = bo(D2Th)*'i 

 where: 



Y = component volume in cubic feet. 



D = dbh in inches 



Th = total height of tree in feet, 



bob, = regression coefficients. 

 ^Standard error in logio form. 

 ^Additional statistics for computation of confidence intervals: 



S(x-x)2 = 4.3559 and x = 3.9631 for equations based on 28 trees and 



S(x-xr = 0.5386 and x = 4.4520 for equations based on 16 trees.
