Analysis of extreme events [40]

Go to: Summary | Previous | Next   
Bullet points include: Model with a mixture of multivariate Normal distributions (or GPDs, …) Time-stationary? Maybe not realistic? Time-varying? (Discrete) regime switching, and/or (Continuous) parameterisation (and continuous time?) However: Even a mixture of just two multivariate Normal distributions involves estimation of twice as many parameters Results even more sensitive to input assumptions Time varying => dynamic => sensitivity to transaction costs
