WebDec 16, 2013 · Excel Solver is one of the good computer procedure to do this. You firstly input the function f (alpha, beta, omega) in one of the cells in Excel e.g. A1 (well this has more to say later, actually). Then you call out the Solver app. It will ask you to enter which cell you wanna maximize. You choose Cell A1. WebThen, we can define a vector of zero-mean white noises ε t = rt − μ, where rt is the n × 1 vector of returns and μ is the vector of expected returns. Despite being serially uncorrelated, the returns may present contemporaneous correlation. That is: ∑ t = Ε t - 1 [ ( r t - μ) ( r t - μ) ′] may not be a diagonal matrix.
