Computes MUKV for given geostatistical parameters
calculateMukv(observations, predGrid, model, formulaString, ...)
observations |
Data frame with x,y coordinates of observations and possible covariates |
predGrid |
Data frame with x,y coordinates of prediction locations |
model |
Variogram model:object of class variogramModel , of the form
created by vgm |
formulaString |
formula that defines the dependent variable as a linear model
of independent variables; suppose the dependent variable has name z ,
for ordinary and simple kriging use the formula z~1 ;
for universal kriging, suppose z is linearly dependent on
x and y , use the formula z~x+y . The formulaString defaults
to "value~1" if value is a part of the data set.
If not, the first column of the data set is used. |

other arguments to be passed on at lower level functions |
This function computes kriging on the predGrid
with
krige
function, and averages the kriging variance (MUKV). With covariates,
the function takes a universal kriging model into account.
