The distribution of {ri1 , . . , riT } for a given asset i). In this book, we focus on both. In the univariate analysis of Chapters 2–7, our main concern is the joint distribution of {rit }Tt=1 for asset i. To this end, it is useful to partition the joint distribution as F (ri1 , . . , riT ; θ ) = F (ri1 )F (ri2 |ri1 ) · · · F (riT |ri,T −1 , . . , ri1 ) T = F (ri1 ) F (rit |ri,t−1 , . . 15) t=2 where, for simplicity, the parameter θ is omitted. This partition highlights the temporal dependencies of the log return rit .

Not all financial time series are linear, however. We study nonlinearity and nonlinear models in Chapter 4. For a linear time series in Eq. 4), the dynamic structure of rt is governed by the coefficients ψi , which are called the ψ weights of rt in the time series literature. 5) i=0 where σa2 is the variance of at . Because Var(rt ) < ∞, {ψi2 } must be a convergent sequence, that is, ψi2 → 0 as i → ∞.
