Reading for Week 7

I would like to change the scheduled topic for my module's last lecture this term, on 10/17, from CW's treatment of baskets to a review of the dominant conditional heteroskedasticity model, TGARCH.

The main reference for this is

Zakoin, Jean-Michel, Threshold heteroskedastic models, Journal of Economic Dynamics and Control, vol. 18, 1994, pp. 931-955

This journal is avaialble online through the library.

Historical Simulation

I have updated the case from yesterday to demonstrate the failure of the Cholesky method for simulating large vectors, and the alternate historical simulation method. I have also posted a note defining and justifying the method.
