DisjunctiveKriging

Disjunctive kriging: simple kriging of the Hermite factors of the Gaussian transform, giving local grades and proportions above cutoffs.

fit method descriptor

fit(coords, values)

Raw values, or the column of coords holding them; they are Gaussian-transformed with the anamorphosis.

from_parquet staticmethod

from_parquet(path)

Reads to_parquet output; raises InvalidInput on another class's file or a newer format.

predict method descriptor

predict(targets)

Local grade estimates.

predict_tonnage method descriptor

predict_tonnage(targets, cutoff)

Local proportion above cutoff.

to_parquet method descriptor

to_parquet(path)

Writes arrays as Parquet columns and parameters as JSON in the file metadata; from_parquet reads it back.
