To make a cubic model you will need at least points. With these points you can find using basic algebra or with matrices.

What other information do you have? - April 19th 2010, 04:21 PMNerdilicious

Before you attempt substitution do you have a start year (or initial point) for the data?

Otherwise will mean the year and maybe not representative of what you are trying to model. - April 19th 2010, 04:29 PMNerdilicious
No, the data starts at 1950. Could I possibly translate the data so that 1950 is my start date?

So that would make d=554.8, right?

Then would I substitute that in the other equations, or should I use matrices? - April 19th 2010, 05:53 PMpickslides
