Chapter 6: Curve Fitting - McMaster University
Chapter 6: Curve FittingTwo types of Curve Fitting Least square regressionGiven data for discrete values, derive a single Curve that represents the generaltrend of the data. When the given data exhibit a significant degree of error or noise. InterpolationGiven data for discrete values, fit a Curve or a series of curves that pass di-rectly through each of the points. When data are very I: Least Square Regression1 Simple Linear RegressionFitting a straight line to a set of paired observations(x1, y1),(x2, y2).
† Interpolation Given data for discrete values, fit a curve or a series of curves that pass di- ... † The problem of determining a least-squares second order polynomial is equiv-alent to solving a system of 3 simultaneous linear equations.
