Function generic_stability 

pub fn generic_stability(
    data: &FdMatrix,
    y: &[f64],
    scalar_covariates: Option<&FdMatrix>,
    ncomp: usize,
    n_boot: usize,

) -> Option<StabilityAnalysisResult>

Generic explanation stability via bootstrap resampling.

Refits the model on bootstrap samples and measures variability of coefficients, β(t), and metric (R² or accuracy).

Note: This only works for regression and logistic models since it requires refitting. For classification models, bootstrap refitting is not yet supported.
