Re: Black Equation for Option ON Future

One of the great things about maths is how one so often comes up against obstacles requiring taking a different route. And if pupils don't learn this early on then they are doomed to suffering from fear of maths later on. A teacher can demonstrate this by getting things wrong, often and in public!!...

Re: Bivariate Normal Integral paper

Concluding: . The West and Quantlib implementations of the Genz algorithms give the same accuracy up to machine precision. We used the finite difference method to check them just to ensure that they do not give the same incorrect value for certain values of the parameters. We generated a,b,rho rando...
