ExperimentalVariogram

Lag centers, semivariances and pair counts; covariances holds C(h) for the covariance estimator, ρ(h) for the correlogram, and is None otherwise.

length_unit property

length_unit

Length unit of the lags and ranges; None when not declared.

unit property

unit

Unit of the values; semivariances and sills are in its square.

fit method descriptor

fit(
    model=Ellipsis,
    *,
    weighting="count",
    nugget=None,
    sills=None,
    ranges=None,
)

Weighted least-squares fit; see Variogram.fit.

nugget method descriptor

nugget(*, lags=3)

Nugget extrapolated to zero lag from the first lags lags.

Intercept of a pair-count-weighted straight line through them, with intercept and slope kept non-negative. Meant for a downhole variogram (holes= in experimental_variogram), whose shortest lags are the closest pairs available.

Parameters:

Name	Type	Description	Default
lags	int	Number of shortest lags, at least 2.	3
