HermiteAnamorphosis

Gaussian anamorphosis expanded in Hermite polynomials.

block method descriptor 

block(r)

Block anamorphosis for change-of-support coefficient r in (0, 1].

fit method descriptor 

fit(values, *, weights=None, data=None)

values and weights may name columns of data.

from_json staticmethod 

from_json(text)

Reads to_json output; raises InvalidInput on another class's JSON or a newer format.

grade_tonnage method descriptor 

grade_tonnage(cutoffs)

Recoveries above each cutoff, as proportions of the whole.

Returns:

Type Description

cutoff; tonnage, the proportion above cutoff; mean_grade above cutoff, null when nothing is above; metal, tonnage × mean_grade; and benefit, metal - cutoff × tonnage.

inverse_transform method descriptor 

inverse_transform(scores, *, data=None)

Gaussian scores to raw values.

to_json method descriptor 

to_json()

JSON of the parameters and, once fitted, the fitted state.

transform method descriptor 

transform(values, *, data=None)

Raw values to Gaussian scores.
