Re: [Quantlib-dev] GJR-GARCH option pricing engine

Hi Luigi

   Thanks for your reply. Are you still at Stanford?
Maybe we can hang out one day.

   I will start coding then. It shouldn't be too hard.
I can just copy the Heston code and change the
stochastic process for volatility. I also have an
implementation for analytical approximation of
GJR-GARCH option pricing model as described in Duan
2004 paper. 

   Do you guys give out remote CVS access for
developers? That's what I got for my previous open
source contribution. If this is not how it works here,
I am ok sending files directly to Luigi.

Have a great day!
