interpreting product A-2 >=1.978

Dear Jamie,

Thanks for the reply.

We have another problem to solve.

on the node we are getting product A -2 >=1.978

What does it mean (-2) ?

It is mentioned as two time slices ago. Please help me to undertand this.

From

menik

that is exactly the meaning. For example take the series

1, 3, 5, 6, 4, 2, 3

Say I have a tree that says "If (A-2) > 2 then result = (A-1 * 0.75) else result = (A-1 * 1.25)"

The next prediction in the series would be (3*1.25)=3.75 as (A-2) is 2 (not greater than two) and (A-1) is 3. The following prediction would be (3.75 * 0.75)=2.81 as (A-2) in this case is now 3, and (A-1) is the newly predicted value 3.75
