In RobustCalibration: Robust Calibration of Imperfect Mathematical Models

Fast prediction when the test points lie on a 2D lattice.

Description

This function computes fast computation when the test points lie on a 2D lattice.

Usage

predict_separable_2dim(object, testing_input_separable,
X_testing=matrix(0,length(testing_input_separable[[1]])*
length(testing_input_separable[[2]]),1), n_thinning=10,  
interval_est = NULL,math_model=NULL,test_loc_index_emulator=NULL,...)

Arguments

object	an object of class rcalibration.
testing_input_separable	a list. The first element is a vector of the coordinate of the latitue and the second element is a vector of the coordinate of the longitude.
X_testing	a matrix of mean/trend for prediction.
n_thinning	number of points thinning the MCMC posterior samples.
math_model	a function for the math model to be calibrated.
test_loc_index_emulator	a vector of the location index from the ppgasp emulator to output. Only useful for vectorized output computer model emulated by the ppgasp emulator.

Value

The returned value is a S4 CLass predictobj.rcalibration.
