OrdKrig_optim_krige: Optimization function local ordinary kriging

In JBrenn/SpatialInterpol: Spatial Interpolation of Soil Variables | Province of Bolzano

Description

Optimization function performing 5-fold validation and returning RMSE of estimates for local ordinary kriging.

Usage

OrdKrig_optim_krige(par = c(cutoff=300, anis_deg=0, anis_ax=.5, nmax=12, omax=3, nugget=1),
                            wpath = "/home/jbre/R/OrdKrig", 
                            datafile = "raw/Masterfile_Adige.txt",
                            variable = "Humus____",
                            model="Sph", kfold=5)

Arguments

par	see optim or hydroPSO. For names of vector par see idw.
wpath	see OrdKrig
datafile	path to and name of the data to optimize on
variable	see OrdKrig
model	see fit.variogram
kfold	see createFolds

Value

RMSE of local ordinary kriging estimations vs. observed data
