Apply a transformer columnwise to multivariate series.

Quickstart

from sktime.transformations.compose import ColumnwiseTransformer

estimator = ColumnwiseTransformer(transformer, columns=None)

Parameters(2)

transformerEstimator

scikit-learn-like or sktime-like transformer to fit and apply to series.

columnslist of str or None

Names of columns that are supposed to be transformed. If None, all columns are transformed.

Examples

>>> from sktime.datasets import load_longley
>>> from sktime.transformations.detrend import Detrender
>>> from sktime.transformations.compose import ColumnwiseTransformer
>>> _, X = load_longley ()
>>> transformer = ColumnwiseTransformer (Detrender ())
>>> Xt = transformer. fit_transform (X)
