The GARCH models discussed so far are symmetric in that the shock sign does not affect the resulting volatility. In practice, however, negative price shocks influence volatility more than the positive shocks. , ).
2) Calculate the histogram using the Histogram tool of the Data Analysis menu. (3) Divide the histogram frequencies with the product of their sum and the bin size (explain why it is necessary). 4. Let X1 and X2 be two independent copies of the normal distribution X $ N(m, s2 ). Since X is stable, aX1 þ bX2 $ CX þ D. Calculate C and D via given m, s, a, and b. Chapter 4 Stochastic Processes Financial variables, such as prices and returns, are random timedependent variables. The notion of stochastic process is used to describe their behavior.
Positive covariance between two variates implies that these variates tend to change simultaneously in the same direction rather than in opposite directions. Conversely, negative covariance between two variates implies that when one variate grows, the second one tends to fall and vice versa. Another popular measure of simultaneous change is the correlation coefficient Corr(x, y) ¼ Cov(x:y)=(sX sY ) (3:1:14) The values of the correlation coefficient are within the range [ À 1, 1]. In the general case with N variates X1 , .
