_OneSegmentAddConstTransform

class _OneSegmentAddConstTransform(in_column: str, out_column: str, value: float, inplace: bool = True)

Bases: etna.transforms.base.Transform

Init _OneSegmentAddConstTransform.

Parameters

• in_column (str) – column to apply transform

• out_column (str) – name of added column

• value (float) – value that should be added to the series

• inplace (bool) –

  • if True, apply add constant transformation inplace to in_column,

  • if False, add transformed column to dataset

Methods

fit(df)	Fit preprocess method, does nothing in _OneSegmentAddConstTransform case.
fit_transform(df)	May be reimplemented.
inverse_transform(df)	Apply inverse transformation: subtract given value from all the series values.
transform(df)	Transform method: add given value to all the series values.

fit(df: pandas.core.frame.DataFrame) → etna.transforms.math.add_constant._OneSegmentAddConstTransform
