I want my input to have the data integrated from 1990 to 2010 and with that, i want the my estimation function to be able to approximate closing price of 10 years.
I know i have to use probability and statistics theories but i wanted some specific answers about what theory I must use.
I would be glad if you could guide me to the tools that can be used in matlab for the job and also, tutorials too :D
Do you have the curve fitting toolbox? If so, either click on the curve fitting app in the apps gallery or run:
>> cftool
This will pull up an interactive environment for you to do your curve fitting.
As an aside, Ihighly recommend against fitting high order polynomials to anything. They're highly unstable, overfit to noise, are useless for prediction and have no place in physics. If you are trying to fit to something that does not have an analytic model, such as a stock price, use one of the data driven modeling techniques. This webinar might interest you:
