WebFeb 7, 2013 · The variogram function describes how we expect the value of the field to vary given the two positions. It is formally defined. Also note that this function needs to … The squared term in the variogram, for instance , can be replaced with different powers: A madogram is defined with the absolute difference, , and a rodogram is defined with the square root of the absolute difference, . Estimators based on these lower powers are said to be more resistant to outliers. They can be generalized as a "variogram of order α", ,
