Arbitrage-Free Smoothing of the Implied Volatility Surface
The function is an implementation of the method proposed in Fengler, M. (2009). Arbitrage-Free Smoothing of the Implied Volatility Surface. Quantitative Finance, 9:4, 417-428.
The method uses smoothing splines under shape constraints to estimate call option prices as a function of strike and time-to-maturity. Based on these prices, implied volatilities can be obtained.
