Question 17

Multiple Choice

The jth autocorrelation coefficient is defined as


A) cov⁡(Yt,Yt−1) var⁡(YJ) var⁡(Yt−1) \frac { \operatorname { cov } \left( Y _ { t } , Y _ { t } - 1 \right) } { \sqrt { \operatorname { var } \left( Y _ { J } \right) \operatorname { var } \left( Y _ { t } - 1 \right) } }
B) cov⁡(Yt,Yt−j−1) var⁡(Yt) var⁡(Yt−j) \frac { \operatorname { cov } \left( Y _ { t } , Y _ { t } - j - 1 \right) } { \sqrt { \operatorname { var } \left( Y _ { t } \right) \operatorname { var } \left( Y _ { t - j } \right) } }
C) cov⁡(Yt,ut) var⁡(Yt) var⁡(ut) \frac { \operatorname { cov } \left( Y _ { t } , u _ { t } \right) } { \sqrt { \operatorname { var } \left( Y _ { t } \right) \operatorname { var } \left( u _ { t } \right) } }
D) cov⁡(Yt,Yt−j) var⁡(Yt) var⁡(Yt−j) \frac { \operatorname { cov } \left( Y _ { t } , Y _ { t } - j \right) } { \sqrt { \operatorname { var } \left( Y _ { t } \right) \operatorname { var } \left( Y _ { t - j } \right) } }
