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.
