pub fn evaluate_svi(
data: Vec<MarketDataRow>,
params: SVIParams,
calib_params: CalibrationParams,
) -> Result<f64>Expand description
Evaluate the SVI calibration objective for a fixed parameter set.
This produces exactly the same loss value that calibrate_svi minimises
internally, honouring any ATM-boost and vega-weighting settings embedded in
calib_params. It enables external callers (e.g. live monitoring) to
measure model fit quality without re-running the optimiser.
