Largely based on the Fortran IV script appended to the original source. Checked against table VI.1 (ibid), p. 66.
This function was written by Björn Hägglund following the same method as outlined in Hägglund 1972.
Carbonnier_1975_Sweden_height_trajectories_Oak(
total_age,
top_height_m,
age_2,
output = "SIH100"
)
total_age |
total age of stand or tree. |
top_height_m |
Top height of tree or stand in m. |
age_2 |
Necessary if output is "Height". The age for which height along the same curve is to be computed. |
output |
One of "SIH100", "Height", or "Equation". |
multiple correlation coefficient: 0.995
100*spread around the function/spread around the mean: 10.1
spread around the mean of ln(height): 0.30096
If output is "SIH100", the numeric value for the height (m) a stand will reach at age 100.
If output is "Height", the numeric value for the height (m) a stand will reach at age_2.
If output is "Equation", a text response with the equation for that height curve.
