Computes the exponent measure of HR distribution.
V_HR(x, Gamma = NULL, Theta = NULL)Numeric. The exponent measure of the HR distribution.
Numeric vector with d positive elements
where the exponent measure is to be evaluated.
d x d variogram matrix or numeric vector with d(d-1)/2 elements, containing the upper triangular part of a variogram matrix.
d x d precision matrix or numeric vector with d(d-1)/2 elements, containing the upper triangular part of a precision matrix.
Only Gamma is needed for the computation. Theta is only used to
compute Gamma if necessary.
