How to obtain standard error of cumulative effect of binary variable in distributed lag model?

In distributed lag non-linear model, the author used meta-anlysis to get the summarized statistic of cumulative effect. However, it can only to apply numeric function. If I fit the binary variable ...

Why the series to the power of two differs from the expanded AR(2) equation?

I am trying to rewrite the series $\tilde{R}_{t}=\beta_{2}\left(\sum_{s=0}^{\infty}\frac{U_{t-s}}{\phi^{s+1}}\right)^{2}$ as an $AR(2)$ using lag operators $L$. I expand the series, define $\alpha=\...
