Happy coding

If you can get the excel sheet,

you see two parameters which can be adjusted to move the log fit around located in cells p2, and q2. The sum of the squares of the errors (price fit)2 is in cell q8. You ask excel to minimize q8 by change p2 and p3.This is a black box. I didn go through by hand to see if there wholesale nfl jerseys is a fit which works better. There is no mathematical guarantee that the solution excel found is the best, or the only one.Furthermore, it may be suggested that a model is better if it does not minimize the error, but rather finds any condition you like. This is justifiable if you think "there must be greater than minimal error because we know there are fluctuations." You could choose to apply the model in only "reasonable" price zones you can toss out ridiculous price regions.Furthermore you can try to fit the curve cheap nfl jerseys to a high degree polynomial. That may seem a bit crazy.Tl:dr this as a predictive tool is as simple and as limited as it gets. I would trust its results with caution.Something interesting to try would be to add some noise in the demand or supply curves from the more generalized equations and make plots then. Some of the plots generated by that model really did resemble some various local behaviors I have seen from bitcoin.In any cheap jerseys case, we getting rich. There no question cheap nfl jerseys about that. Since that is so clear to me, I dissect this issue out of bordem but with much satisfaction. Bitcoin is just too easy. Buy it.
