Calibration Package#
The calibration
package provides a comprehensive suite of tools for fitting financial models to market data, estimating parameters from historical data, and calculating implied volatility surfaces.
- Calibrator: The main class for orchestrating the optimization process to fit model parameters to market option prices.
- VolatilitySurface: A class to compute and manage implied volatility surfaces from both market and model-generated prices.
- Parameter Fitters: Utility functions to estimate specific parameters, such as
fit_rate_and_dividend
from put-call parity orfit_jump_params_from_history
from historical returns. - Technique Selector: A helper function to automatically select the most efficient pricing technique for a given model.
- IV Solvers: High-performance, vectorized solvers for calculating implied volatility.
