holiday¶

Classes

`HolidayTransform`([iso_code, mode, out_column])	HolidayTransform generates series that indicates holidays in given dataset.
`HolidayTransformMode`(value)	Enum for different imputation strategy.

class HolidayTransform(iso_code: str = 'RUS', mode: str = 'binary', out_column: Optional[str] = None)[source]¶

HolidayTransform generates series that indicates holidays in given dataset.

In binary mode shows the presence of holiday in that day. In category mode shows the name of the holiday with value “NO_HOLIDAY” reserved for days without holidays.

Create instance of HolidayTransform.

Parameters

iso_code (str) – internationally recognised codes, designated to country for which we want to find the holidays
mode (str) – binary to indicate holidays, category to specify which holiday do we have at each day
out_column (Optional[str]) – name of added column. Use self.__repr__() if not given.

fit(ts: etna.datasets.tsdataset.TSDataset) → etna.transforms.base.Transform¶

Fit the transform.

Parameters: ts (etna.datasets.tsdataset.TSDataset) – Dataset to fit the transform on.
Returns: The fitted transform instance.
Return type: etna.transforms.base.Transform

fit_transform(ts: etna.datasets.tsdataset.TSDataset) → etna.datasets.tsdataset.TSDataset¶

Fit and transform TSDataset.

May be reimplemented. But it is not recommended.

Parameters: ts (etna.datasets.tsdataset.TSDataset) – TSDataset to transform.
Returns: Transformed TSDataset.
Return type: etna.datasets.tsdataset.TSDataset

get_regressors_info() → List[str][source]¶

Return the list with regressors created by the transform. :returns: List with regressors created by the transform.

Return type: List[str]

inverse_transform(ts: etna.datasets.tsdataset.TSDataset) → etna.datasets.tsdataset.TSDataset¶

Inverse transform TSDataset.

Do nothing.

Parameters: ts (etna.datasets.tsdataset.TSDataset) – TSDataset to be inverse transformed.
Returns: TSDataset after applying inverse transformation.
Return type: etna.datasets.tsdataset.TSDataset

classmethod load(path: pathlib.Path) → typing_extensions.Self¶

Load an object.

Warning

This method uses dill module which is not secure. It is possible to construct malicious data which will execute arbitrary code during loading. Never load data that could have come from an untrusted source, or that could have been tampered with.

Parameters: path (pathlib.Path) – Path to load object from.
Returns: Loaded object.
Return type: typing_extensions.Self

params_to_tune() → Dict[str, etna.distributions.distributions.BaseDistribution]¶

Get grid for tuning hyperparameters.

This is default implementation with empty grid.

Returns: Empty grid.
Return type: Dict[str, etna.distributions.distributions.BaseDistribution]

save(path: pathlib.Path)¶

Save the object.

Parameters: path (pathlib.Path) – Path to save object to.

set_params(**params: dict) → etna.core.mixins.TMixin¶

Return new object instance with modified parameters.

Method also allows to change parameters of nested objects within the current object. For example, it is possible to change parameters of a model in a Pipeline.

Nested parameters are expected to be in a <component_1>.<...>.<parameter> form, where components are separated by a dot.

Parameters

**params – Estimator parameters
self (etna.core.mixins.TMixin) –
params (dict) –

Returns

New instance with changed parameters

Return type

etna.core.mixins.TMixin

Examples

>>> from etna.pipeline import Pipeline
>>> from etna.models import NaiveModel
>>> from etna.transforms import AddConstTransform
>>> model = model=NaiveModel(lag=1)
>>> transforms = [AddConstTransform(in_column="target", value=1)]
>>> pipeline = Pipeline(model, transforms=transforms, horizon=3)
>>> pipeline.set_params(**{"model.lag": 3, "transforms.0.value": 2})
Pipeline(model = NaiveModel(lag = 3, ), transforms = [AddConstTransform(in_column = 'target', value = 2, inplace = True, out_column = None, )], horizon = 3, )

to_dict()¶: Collect all information about etna object in dict.

transform(ts: etna.datasets.tsdataset.TSDataset) → etna.datasets.tsdataset.TSDataset¶

Transform TSDataset inplace.

Parameters: ts (etna.datasets.tsdataset.TSDataset) – Dataset to transform.
Returns: Transformed TSDataset.
Return type: etna.datasets.tsdataset.TSDataset

class HolidayTransformMode(value)[source]¶: Enum for different imputation strategy.
