Model	Taper Equation
Max and Burkhart (1976)	d = D B H b 1 ( h H − 1 ) + b 2 ( h 2 H 2 − 1 ) + b 3 ( a 1 − h H ) 2 I 1 + b 4 ( a 2 − h H ) 2 I 2 where d = diameter outside bark at height (cm)DBH = diameter at breast height outside bark (cm)h = height along stem (m)H = total height (m)bi = parametersai = parameters (i=1; upper, i=2; lower)	Ii = 1, if h H < a i 0, otherwise
Kozak (1988)	d = a 1 D B H a 2 a 3 D B H X b 1 Z 2 + b 2 ln ( Z + 0.001 ) + b 3 Z + b 4 e Z + b 5 ( D B H H ) where Z = relative height ( = h H ) X = 1 − h H 1 − p ( p = H I H , HI; inflection point)ai, bi = parameters
Lee (1994)	d x = b 1 ⋅ D B H 2 b ⋅ ( 1 − x h ) [ c 1 ⋅ ( x h ) 2 + c 2 ⋅ ( x h ) + c 4 ] where x h = relative height
