AddConstTransform

class AddConstTransform(in_column: str, value: float, inplace: bool = True, out_column: Optional[str] = None)

Bases: etna.transforms.base.ReversibleTransform

AddConstTransform add constant for given series.

Init AddConstTransform.

Parameters

• in_column (str) – column to apply transform

• 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

• out_column (Optional[str]) – name of added column. If not given, use self.__repr__()
