Equation 2yRGR (live oak) = 0.807 − 0.121 initial branch diameter r2 = 0.559, regression model P < 0.001
Equation 3zRGR (shumard oak) = 1.93 − 0.361 initial branch diameter r2 = 0.462, regression model P < 0.001
Equation 4zRGR (live oak) = 0.674 − 0.583 aspect ratio r2 = 0.338, regression model P < 0.001
Equation 5zRGR (shumard oak) = 1.96 − 1.90 aspect ratio r2 = 0.42, regression model P < 0.001

  • ↵zConfidence intervals at α = 0.05 reject zero slope line in scatterplot.

  • ↵yPrediction intervals at α = 0.05 reject zero slope line in scatterplot.

  • RGR = relative growth rate.
