Polynomial Regression

W

walter

I have a time series (x) and a set of known y's.

When plotted the polynomial trend gives the strongest R-
square (strength to the linear relation). The equation is
along the lines of y = ax^2 + bx + c.

How can I get the coeffients of a, b & c by formula.

To put it another way I what to calc the polynomial value
of y for each x to calc the variance.

I have done this for linear and log regression already but
have had no luck on polynomials.
