— MSR indicates mean square residuals. For logarithmic functions, MSR was calculated 

 as Z(P-0)^/df, where P and are predicted and observed values transformed to arithmetic 

 units and df is the residual degrees of freedom.

Range in d.b.h. for sample trees, 



These equations are of the form Iny = a + blnX + (mean square error/2] . The latter 

 term corrects for bias in transforming logs and is included in the intercept term in the 

 equations. The intercept term was adjusted by (mean square/2) when the summation of pre- 

 dicted minus observed values in arithmetic units showed less bias with the correction term 

 than without it.
