Hello.I'd like to ask you some assistance on implementing the HW2F model. I've seen some postings on the Monte Carlo approach but I haven't much discussion on the tree approach. Brigo & Mercurio's book on implementing the HW2F model involves a recombining binomial tree and mentions also the simulation approach. This site explains another tree approach but using an approach which basically involves using two trinomial trees: http://www-rocq.inria.fr/mathfi/Premia/ ... 1-40002.1I am not entirely sure what is the best approach, particularly for valuing MBS. Could someone provide some insight as to the pros/cons of the tree vs MC approach as well as some tips on which "tree" is better, particularly for this instrument. Is the tree better for long term rate projections? Through this forum, I found a VBA example where this has been done but since I'm rather new at this, I need to first understand what and why. Thank you so much!
