Method update()

Update the model, can be data and parameters

Usage

GauPro_Gauss_LOO$update(
  Xnew = NULL,
  Znew = NULL,
  Xall = NULL,
  Zall = NULL,
  restarts = 5,
  param_update = self$param.est,
  nug.update = self$nug.est,
  no_update = FALSE
)

Arguments

Xnew

New X matrix

Znew

New Z values

Xall

Matrix with all X values

Zall

All Z values

restarts

Number of optimization restarts

param_update

Should the parameters be updated?

nug.update

Should the nugget be updated?

no_update

Should none of the parameters/nugget be updated?

---

Method pred_one_matrix()

Predict mean and se for given matrix

Usage

GauPro_Gauss_LOO$pred_one_matrix(XX, se.fit = F, covmat = F)

Arguments

XX

Points to predict at

se.fit
