pref.4PG: Measured and simulated data from PREF, northern Idaho, USA, and 4-PG
Description
These data are the juxtaposition of model output and field measurements
for the Priest River Experimental Forest in northern Idaho, USA. The
model was a process-based aspatial forest stand model called 4-PG,
developed from 3-PG by Duursma (2004). The data were used to demonstrate
a regression-based TOST in Robinson et al (2005).
Usage
data(pref.4PG)
Arguments
Format
A dataset with 35 observations on 33 variables, of which the
following two were used for the model validation exercise.
stemvolinc
measured decadal stem growth in $m^3/ha$
volinc4PG
predicted decadal stem growth in $m^3/ha$
Source
The data are documented in Duursma (2004) and Robinson et al (2005).
Details
Nothing in particular. Devil's club (Oplopanax horridus)
is very painful.
