LinearlyInterpolateTS	Transformer that applies linear interpolation to time series data.

LinearlyInterpolateTS

preprocessing.linearly_interpolate_ts.LinearlyInterpolateTS()

Transformer that applies linear interpolation to time series data.

This transformer fills missing values using linear interpolation and forward-fills any remaining gaps (e.g., at the end of the series).

Examples

>>> import pandas as pd
>>> import numpy as np
>>> from spotforecast2_safe.preprocessing.linearly_interpolate_ts import LinearlyInterpolateTS
>>> s = pd.Series([1.0, np.nan, 3.0, np.nan])
>>> interpolator = LinearlyInterpolateTS()
>>> s_filled = interpolator.fit_transform(s)
>>> s_filled.tolist()
[1.0, 2.0, 3.0, 3.0]

Methods

Name	Description
