Predictive results for the Fast GaSP class
Description
S4 class for prediction for a Fast GaSP model with or without a noise.
Objects from the Class
Objects of this class are created and initialized with the function predict
that computes the prediction and the uncertainty quantification.
Slots
num_testing
:object of class
integer
. Number of testing inputs.testing_input
:object of class
vector
. The testing input locations.- param
a vector of parameters. The first parameter is the natural logarithm of the inverse range parameter in the kernel function. If the data contain noise, the second parameter is the logarithm of the nugget-variance ratio parameter.
mean
:object of class
vector
. The predictive mean at testing inputs.var
:object of class
vector
. The predictive variance at testing inputs. If thevar_data
is true, the predictive variance of the data is calculated. Otherwise, the predictive variance of the mean is calculated.var_data
:object of class
logical
. If thevar_data
is true, the predictive variance of the data is calculated forvar
. Otherwise, the predictive variance of the mean is calculated forvar
