Web1Factor Models The Markowitz mean-variance framework requires having access to many parameters: If there are n risky assets, with rates of return r i,i=1,2,...,n,then we must know all the n means (r i), n variances (σ2 i) and n(n − 1)/2covariances (σ ij) for a total of 2n + n(n − 1)/2 parameters.If for example n = 100 we would need 4750 parameters, and if n = … WebOther short rate models One-factor Hull-White model Some of these shortcomings can be easily overcome by means of a slight extension of the model. A suitable generalization of the Ornstein-Uhlenbeck process (2) is a process which mean reverts to a time dependent level (t) rather than a constant . Such a process is given by dr (t) = d (t) dt
