Covariogram
= Covariogram
{title2=$C(h)$}
The <covariogram> is the displacement-dependent <covariance> $C(h)=\operatorname{Cov}[Z(s+h),Z(s)]$ of a second-order stationary field. It is an even <positive-definite kernel>. A <semivariogram> determines differences $C(0)-C(h)$, but not an arbitrary constant <covariance> component.
