OLSModel

Ordinary Least Squares linear regression using scikit-learn’s LinearRegression.

Basic Usage

from epftoolbox2.models import OLSModel

model = OLSModel(
    predictors=[
        "load_actual",
        "is_monday_d+{horizon}",
        "is_tuesday_d+{horizon}",
        "is_wednesday_d+{horizon}",
        "is_thursday_d+{horizon}",
        "is_friday_d+{horizon}",
        "is_saturday_d+{horizon}",
        "is_sunday_d+{horizon}",
        "is_holiday_d+{horizon}",
        "daylight_hours_d+{horizon}",
    ],
    training_window=365,
    name="OLS",
)
