search_LB_prob {RobustGaSP} | R Documentation |
Search for the default lower bound of range parameters.
Description
Function to find the values to construct the default lower bound of range parameters.
Usage
search_LB_prob(param, R0, COND_NUM_UB, p, kernel_type, alpha, nugget)
Arguments
param |
A vector of natural logarithm of inverse-range parameters and natural logarithm of the nugget-variance ratio parameter. |
R0 |
A List of matrix where the j-th matrix is an absolute difference matrix of the j-th input vector. |
COND_NUM_UB |
The maximum condition number of the correlation matrix. |
p |
|
kernel_type |
Type of kernel. |
alpha |
Roughness parameters in the kernel functions. |
nugget |
The nugget-variance ratio parameter if this parameter is fixed. |
Value
A vector
of values used in constructing the default lower bound of range parameters.
