semivariance

In spatial statistics, semivariance can be described by

\gamma(h)=\sum_{i=1}^{n(h)}\frac{(z(x+h)-z(x))^2}{n(h)}

where z is a data value at a particular location, h is the distance between data values, and n(h) counts the number of pairs of data values we are given, spaced a distance of h apart. A plot of the semivariance versus distance between data values is known as a semivariogram, or simply as a variogram. See also: geostatistics, kriging
