Jelaskan Kontroversi dari Variogram dalam bahasa sunda

In mathematical statistics, a set of n méasured values gives df=n-1 degrees of freedom wheréas the in situ or temporally ordered set gives df(o)=2(n-1) degrees for the first variance term. The variogram and semivariogram are both invalid méasures for variability, precision and risk because the sum of squared differences between x and x+h is divided by n''', the number of data in the set rather than by df(o)=2(n-1)'', the degrees of freedom for the first variance term of the ordered set.
