Jun 9, 2019 at 16:34 | comment | added | Clarice Taylor | That's why, $ Y_t $ ~ $ intercept + Y_{t-1} + X_{1,t} + X_{2,t} + X_{3,t} + X_{1,t-2} + X_{3, t-4} $ because the ACF of $ Y $ shows it has lag 1, and t1 = 2, t2 = 0, and t3 = 4. | |
Jun 9, 2019 at 16:31 | comment | added | Clarice Taylor | Hi @mdewey I really appreciate your comment. To be clear, $ Y_t $ is count data at time t, and I wanna regress it to its explanatory variables $ X_{1,t−t1} $, $ X_{2,t-t2} $ , $ X_{3,t-t3} $, and $ Y_{t-lag} $ as well. t1,t2, and t3 are chosen depending on the cross-correlation between Y and $ X_1 $ , $ X_2 $, and $ X_3 $ respectively. For example, from the cross-correlation between Y and $ X_1 $, we get the high correlation is when $ X_1 $ is lagged 2. so I put the $ X_{1,t-2} $ as the explanatory variable. | |
Jun 9, 2019 at 14:43 | comment | added | mdewey | I think you need to clarify this some more. Why do the predictors include $X_{1,t-2}$ rather than $X_{1,t-1}$? | |
