The above plots are an example of y = f (x) polynomial least squares curve fits of the same data. The 6th
order polynomial curve fit satisfies the condition where the curve fit passes through each of
the six data points. The form of the equation for the 2nd order linear curve fit is:
y = a0 + a1x
The form of the equation for the 6th order curve fit is:
y = a0 + a1x + a2x2 + a3x3 +
a4x4 + a5x5
The software also includes the data plotting routine PlotXYZ and the
Statistical Analysis program.
