Rapid determination of chemical composition and classification of bamboo fractions using visible–near infrared spectroscopy coupled with multivariate data analysis

Table 4 Results of juvenile bamboo and mature bamboo predicted by identification models based on PLS-DA

Wavelength (nm)	Type	No. of prediction samples	Correct no.	Accuracy (%)
400–780 (n = 160)	Juvenile bamboo	24	24	100
400–780 (n = 160)	Mature bamboo	40	40	100
780–2500 (n = 160)	Juvenile bamboo	24	24	100
780–2500 (n = 160)	Mature bamboo	40	40	100
400–2500 (n = 160)	Juvenile bamboo	24	24	100
400–2500 (n = 160)	Mature bamboo	40	40	100

Three regions of wavelength were selected to establish models, and these spectra came from original data. The number of juvenile bamboo and mature bamboo samples were 60 and 100, respectively
