S. interest rates from April 1953 to February 2009: (a) 10-year Treasury constant maturity rate and (b) 1-year maturity rate. S. dollar and Japanese yen from January 4, 2000, to March 27, 2009: (a) exchange rate and (b) changes in exchange rate. Treasury constant maturity rates from April 1954 to February 2009. As expected, the two interest rates moved in unison, but the 1-year rates appear to be more volatile. S. dollar and the Japanese yen from January 4, 2000, to March 27, 2009. From the plot, the exchange rate encountered occasional big changes in the sampling period.

Then the lag-1 sample autocorrelation of rt is ρˆ1 = T t=2 (rt − r¯ )(rt−1 − T 2 t=1 (rt − r¯ ) r¯ ) . Under some general conditions, ρˆ1 is a consistent estimate of ρ1 . 2). This result can be used in practice to test the null hypothesis H0 : ρ1 = 0 versus the √ alternative hypothesis Ha : ρ1 = 0. The test statistic is the usual t ratio, which is T ρˆ1 and follows asymptotically the standard normal distribution. 05. In general, the lag- sample autocorrelation of rt is defined as ρˆ = T t= +1 (rt − r¯ )(rt− T 2 t=1 (rt − r¯ ) − r¯ ) , 0≤ < T − 1.

T }. One can also consider the simple returns {Rit ; i = 1, . . , N ; t = 1, . . , T } and the log excess returns {zit ; i = 1, . . , N ; t = 1, . . , T }. 1 Review of Statistical Distributions and Their Moments We briefly review some basic properties of statistical distributions and the moment equations of a random variable. Let R k be the k-dimensional Euclidean space. A point in R k is denoted by x ∈ R k . Consider two random vectors X = (X1 , . . , Xk ) and Y = (Y1 , . . , Yq ) . Let P (X ∈ A, Y ∈ B) be the probability that X is in the subspace A ⊂ R k and Y is in the subspace B ⊂ R q .
