Lagged relationship creation

[rookiestat]

Hello,

I need to create formula like

x(1995)=x(1994)+y(change from 1994 to 1995), where I know y and x(1994) but I do not know x from 1995 and later, and I want it to be autoupdating

when I try to do it with

frml x=x(-1)+y

it gives me circular reference error.

Is there any other way to do it?

Thank you!

There is not - the autoupdating requirement makes it impossible.

Thank you for your answer!

What would be a solution if not autoupdating?

[EViews Gareth]

series x=x(-1)+y

[startz]

series x=x(-1)+y

But be sure to set the first value of x

Code: Select all

smpl 1994 1994 series x = 3.14159 smpl 1995 @last x = x(-1) + y
