    Polynomial Regression Data Fit. For a given data set of x,y pairs, a polynomial regression of this kind can be generated:

    f(x)=c0+c1x+c2x2+c3x3...

    In which c0,c1,c2... represent coefficients created by a mathematical procedure described in detail here. In this regression method, the choice of degree and the evaluation of the fit's quality depend on judgments that are left up to the user. It is well known about this class of regression method that an effort to squeeze more correlation out of the algorithm than the data can support will sometimes produce an out-of-control function that, although it matches the data points, wanders wherever it pleases between those points. Therefore, a "good" (approaching 1.0) correlation coefficient is not enough to assure a well-behaved or meaningful function. Decisions about a result's appropriateness is more a matter of judgment than mathematics. A "perfect" fit (one in which all the data points are matched) can be gotten by setting the degree of the regression to the number of data pairs minus one. But, depending on the nature of the data set, this can also sometimes produce the pathological result described above in which the function wanders freely between data points in order to match the data exactly.

    For those seeking a standard two-element linear regression, select polynomial degree 1 below, and for the standard form —

    f(x)=mx+b

    b corresponds to be the first parameter listed in the results window below, and m to the second.
