How to make a lagged variable in panel data?
Suppose we observe N individuals, for each of which we have a
time-series. How do we correctly create a lagged value of the
time-series variable?
As an example, suppose I create:
A <- data.frame(year=rep(c(1980:1984),3),
person= factor(sort(rep(1:3,5))),
wage=c(rnorm(15)))

ts startdate
...4) performing
n-steps-ahead (6) forecasts and using a fixed window size (36). At the
end of calculations I have a list that contains 69 forecasts.
I have no problems in fixing the window size by parametrization, e.g.
k<- control variable in a for loop
my.length<-36
past<-window(X,start=c(1980,k - my.length + 1),end=c(1980,k))
The integer defining the month number can be arbitrary set to: 6,16,46

parameterise the start date of the result list
