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

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

Wavelength (nm) Type No. of prediction samples Correct no. Accuracy (%)
400–780 (n = 160) Juvenile bamboo 24 24 100
Mature bamboo 40 40 100
780–2500 (n = 160) Juvenile bamboo 24 24 100
Mature bamboo 40 40 100
400–2500 (n = 160) Juvenile bamboo 24 24 100
Mature bamboo 40 40 100
  1. 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
