matern_3_2_deriv {RobustGaSP} | R Documentation |
The derivative of matern correlation function (roughness parameter equal to 3/2) with regard to the inverse range parameter
Description
This function computes the derivative of a correlation matrix using 1-dimensional matern correlation function (roughness parameter equal to 3/2), with regard to the inverse range parameter.
Usage
matern_3_2_deriv(R0_i, R, beta_i)
Arguments
R0_i |
an absolute difference matrix of the i-th input vector. |
R |
the correlation matrix. |
beta_i |
the inverse range parameter. |
Value
A matrix in which each element is the derivative of 1-dimensional matern correlation function with regard to the inverse range parameter.
