I have a time series that looks like this:
year a b event x
1 1950 0.033222 2 0 1055.461
2 1950 0.033222 345 0 1055.461
3 1950 0.033222 290 0 1055.461
4 1950 0.033222 355 0 1055.461
5 1950 0.033222 710 1 1055.461
6 1950 0.033222 36 0 1055.461
I want to know what happens to x over time when the dummy variable "event" goes to 1. Moreover, I would like to know the effect over 30 years. So my problem is that there might be some other 1 that will appear 12 or 21 years later for example. How can I control for one single event or take into account all the event that might arise during 30 years?
I would like to have something like:
lm(x~event, data=data)
where x is at year t and event all the events that occurred the 30 previous years
I wanted to use VAR package but I don't see how you can add a dummy in their function.
