Leading / Lagging a Series

[w_nawfal]

Question to the Gallery

Eviews is funny in the sense that if i would like to take the rate of change of a series (i.e. s) i can do the follwoing x/(x-1)

where here the x(-1) means the value for x @ n-1 time

however, if i would like to plot the series x and lag it by one peried i must graph x(+1)

why?

EViews always uses X(-1) for lag. I don't know what you mean about needing to use X(+1) for graphs (which would actually graph the one period lead of X, not lag).

Hello Gareth

my confusion stemmed from the fact that when Eviews lags a series it in facts pushes the data forward by n values so that a historical value is matched with a current date.

i.e. if i want a series lagged 3 days i would use x(-3), and when i open this series along with the original I would observe that the new series has 3 more data points than the older one - of course this is done so that the data point of 3 days ago is now the data point for today.

all's well now :O) - I thank you for your reply.
