Age reference plots

Age and sex reference plots for visualizing datasets

get_gam_expectiles

 get_gam_expectiles (X:numpy.ndarray, y:numpy.ndarray,
                     expectiles:List[float]=[0.03, 0.1, 0.5, 0.9, 0.97])

Fit Expectile Generalized Additive Models (GAMs) for given expectiles.

Args: X (ndarray): Feature data for the model. y (ndarray): Target variable for the model. expectiles (List[float]): List of expectiles to fit. Default is [0.03, 0.1, 0.5, 0.9, 0.97].

Returns: Tuple[ndarray, Dict[str, ndarray]]: A tuple containing a grid of X values for prediction and a dictionary with expectiles as keys and their corresponding model predictions as values.
