Brighton Toy and Model Museum arches and contains a large 1930s 0 gauge model railway layout, 00 gauge model railway town and countryside layouts, and collections of model locomotives, soft toys, puppets and marionettes, construction toys, building construction sets, model ships, radio controlled model aircraft, and farm, circus, zoo and ship toy sets. It also includes displays of diecast models including Matchbox, Dinky Toys, Corgi Toys and Spot-On. Exhibition displays draw on outside guest collections and on varying selections taken from the Museum's core collection. The museum is a venue for the Brighton Science Festival and the Brighton Fringe. Public train running days are typically
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.
