Multivariate Image Analysis Applied to Cross-Laminated Timber: Combined Hyperspectral Near-Infrared and X-ray Computed Tomography

Table 1

Partial least squares discriminant analysis (PLS-DA) models assessing the predictability of the first and second components based on three different imaged datasets; Near-infrared (NIR), X-ray computed tomography (CT) and NIR correlated with X-ray CT.

PLS-DA	t [1] (%)	t [2] (%)	Sum of t [1] and t [2]
NIR	67.1	24.0	91.1
X-ray CT	27.6	16.5	44.1
NIR correlated with X-ray CT	45.7	13.7	59.4
