However, as it was mentioned previously, the usage of the stable distributions in financial applications is often restricted because of their infinite variance at a < 2. The compromise that retains flexibility of the Levy Probability Distributions 27 distribution yet yields finite variance is named truncated Levy flight. 9), fL (x) is the Levy distribution ‘ is the cutoff length, and C is the normalization constant. Sometimes the exponential cut-off is used at large distances [3] fTL (x) $ exp ( À ljxj), l > 0, jxj > ‘ (3:3:10) Since fTL (x) has finite variance, it converges to the normal distribution according to the central limit theorem.

6) implies that there is no linear correlation between different observations of the white noise. Such a model represents an independently and identically distributed process (IID) and is sometimes denoted IID(0, s2 ). 3). The normal distribution N(0, s2 ) is the special case of the white noise. 9), [x] denotes the greatest integer that does not exceed x. The process yn (t) has the stepwise form: it is constant except the moments t ¼ kh, k ¼ 1, . . , n. 11) become infinite in the limiting case h !

In practice, the multivariate moving average models are rarely used due to some restrictions [1]. Therefore, we shall focus on the vector autoregressive model (VAR) that is a simple extension of the univariate AR model to multivariate time series.
