"Least squares method program is used."
indir.biz Editor: Least squares method, a multivariable polynomial function to fit a table program is used. The values of function arguments sheet spaced rectangular grid may be unstable, ie, n-variable values to a function for the n-dimensional rectangular grid nodes should be taken as the ruler should be. For example, the x and y independent variables, we, for example, for x 6 and y 5 values and functions, each one (x, y) combination and grill for 30 values may be visible, such as:

---

To show data sets with 2 independent variables and N is a table function, and we assume that you want compliance with first-degree and second degree x Y. polynomial for the polynomial will be inserted after

---

z = a0 + a1x + b0y + + b1xy + c1y2 is c1xy2 = (a0 + a1x) + (b0 + b1x) y + (c0 + c1x) y2

where A0, A1, b0, b1, c0, c1 are coefficients to be determined. We have to solve the normal equations in the following set with the least squares method to minimize from now: Now we can download free Polynomial Regression 1.00.
