variography

name summary used in
Structure One nested structure: sill is the partial sill, range the range along the major axis.
Variogram Nugget plus nested structures sharing one anisotropy. 50
ExperimentalVariogram Lag centers, semivariances and pair counts; covariances holds C(h) for the covariance estimator, ρ(h) for the correlogram, and is None otherwise.
experimental_variogram Experimental variogram, omnidirectional unless azimuth is given, or the cross-variogram of values and other. 69
dissemination Degree of dissemination per lag, √π · M(h) / √γ(h). 1
VariogramSet Direct and cross experimental variograms of several variables, indexed by variable pair.
experimental_variograms Every direct and cross experimental variogram of several variables at the same samples. 2
VariogramMap γ on a plane as an angle × lag grid, with the fitted range per angle.
variogram_map Variogram map on the plane spanned by u and v (default: horizontal, angles counter-clockwise from east). 3
h_scatter Head and tail values of pairs lag ± tolerance apart, and their correlation. 1
pairs Nearest pairs between two sets of samples within max_distance, e.g. twin holes or two drilling types. 2
Coregionalization Linear model of coregionalization: nugget and each structure's sills are symmetric positive semi-definite nvar × nvar matrices, else InvalidInput is raised. 4
Transiogram Markov transiogram for categories with the given proportions.
experimental_transiogram Empirical transition probabilities: (lags, probs[lag, i, j], counts).
VariogramVolume γ on a cube of lag vectors, and the principal axes of continuity.
variogram_volume Experimental variogram over a cube of lag vectors, and its principal axes of continuity. 2
local_variogram_parameters Locally varying variogram parameters from moving-window fits. 1
LocalAnisotropy Orientation (azimuth, dip, rake in degrees), range ratios (semi/major, minor/major) and range scales at a set of locations. 4
