Description Usage Format Details Fields Methods Examples

krigingsm is a kriging adapter. It makes the use of the universal distirbution easier

1	# kriging <- krigingsm$new()

An R6Class generator object

It construct a kriging model from the package DiceKriging and it inherits form the sm. The inheritance of the class sm is required when one want to use the universal distribution

model_name: : Default "Kriging"
type: : universal kriging "UK" or simple kriging "SK"

krigingsm$new(x=NULL,y=NULL,parameters = NULL, type= "UK"): Creates a new krigingsm object.
train(): train the surrogate model.
predict(newdata): it predicts the new data.
