Table 3 Direct and indirect path coefficients of various variables affecting basic wood density (Y₁)

From: Wood density and wood shrinkage in relation to initial spacing and tree growth in black spruce (Picea mariana)

	X₁ → Y₁	X₂ → Y₁	X₃ → Y₁	X₄ → Y₁	X₅ → Y₁
X₁→	0.1726	0.3029	− 0.1373	0.3804	0.0356
X₂→	0.0432	1.2110	− 0.6651	0.1206	− 0.0372
X₃→	− 0.0163	− 0.5556	1.4498	− 0.1020	0.0173
X₄→	0.0825	0.1836	− 0.1859	0.7957	0.0240
X₅→	− 0.0420	0.3078	− 0.1709	− 0.1306	− 0.1464

X₁ = log height, X₂ = DBH class, X₃ = stand density X₄ = ring width, X₅ = distance from the pith, X₆ = basic wood density
Major direct path coefficients are highlighted in bold
