Oil Price Modeling: Fun with polynomials

Unread postby smallpoxgirl » Sat 15 Jul 2006, 01:36:28

I was just looking at the eia graph of crude prices over the last 8 years and it occured to me that the prices since May 02 have a fairly smooth curve to them. Just for fun I thought I'd try and fit a polynomial to them and see what I came up with. I let x=the number of days since 4/26/02 (the point at which the curve starts to look smooth to me.) By eyeballing it I came up with a best fit function y=0.000000012*x^3 +0.0045 * x + 27. It fits pretty nicely. It gives today's oil price as $77.67. Not far off. For one year from now it gives a price of $118. For 7/14/2011, it gives the price as an even $500. 8O

I realize it's a pretty limit technique and maybe I shouldn't be wasting my time with it. Just seemed like an interesting observation.

Of a thousand burning bridges
Sifting through the ashes every day
What we thought would never end
Now is nothing more than a memory
The way things were before
I lost my way" - OCMS
