Implied volatility newton raphson
WitrynaThe most widely used technique for the estimation of the implied volatility is the Newton-Raphson iterative algorithm. It involves making an initial guess as to the implied volatility of the option. It then uses the Greek derivative of the option price relative to changes in volatility (the vega) to make a new guess if the initial guess is … http://www.stat.ucla.edu/~nchristo/statistics_c183_c283/statc183c283_implied_volatility.pdf
