Table 2 The parameters of the Richards function in each diameter class

From: Culm height development, biomass accumulation and carbon storage in an initial growth stage for a fast-growing moso bamboo (Phyllostachy pubescens)

DBH class	\(Y = A \times [1 - \exp ( - k \times t)]^{1/(1 - m)}\)
	a	k	m	R ²	RMSE ^a
I	10.46	0.0996	0.8634	0.9898	0.1072
II	11.40	0.1006	0.8490	0.9602	0.5368
