Corgi Toys and sold in large numbers. Some of the best known and most popular models were of cars made famous in film and television such as the Batmobile, Chitty Chitty Bang Bang and James Bond's Aston Martin DB5 – which remains the largest selling toy car ever produced. Although the largest single vehicle type featured in the Corgi Toys range were models of cars from manufacturers around the world, this article sub-divides vehicles into genres, wherever possible, to allow a more detailed look at the variety of models produced by the company. Mettoy became established in Northampton and within six years
Black–Derman–Toy model model has been shown to imply the following continuous stochastic differential equation: For constant (time independent) short rate volatility, formula_7, the model is: One reason that the model remains popular, is that the "standard" Root-finding algorithms—such as Newton's method (the secant method) or bisection—are very easily applied to the calibration. Relatedly, the model was originally described in algorithmic language, and not using stochastic calculus or martingales.
