OrdKrig_optim_idw: Optimization function inverse distance weighting

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

Description

Optimization function performing 5-fold validation and returning RMSE of estimates for inverse distance weighting.

Usage

OrdKrig_optim_idw(par = c(idp = 2.0, maxdist=300, nmax=12, omax=3),
                  wpath = "/home/jbre/R/OrdKrig", 
                  datafile = "master/Masterfile_AdigeVenosta.txt",
                  variable = "Humus____")

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

Value

RMSE of local inverse distance weights estimations vs. observed data
