Yes, variograms of weakly stationary random fields have a sill: the variance of the field. > and intrisic hypothesis variograms have no sill. They might have no sill, but they also might have. The intrinsic hypothesis is more general than weakly stationary random fields and includes fields with and without sill. > Does this mean intrisic hypothesis variograms > indicate a trend. No, a trend is indicated by a variogram increasing as h^2 for long distances but legal intrinsic variograms increase more slowly than h^2 e.g. as h^1 Best regards, Gerald v.d.
