As described in Chapter 8, the CenterSpace.NMath.Core namespace includes classes for calculating least squares fits of linear functions to a set of points. In addition, the class PolynomialLeastSquares, performs a least squares fit of a Polynomial to a set of points.
This chapter describes how to use class PolynomialLeastSquares.
NOTE—For testing the goodness of fit of PolynomialLeastSquares fits, see class GoodnessOfFit. Available statistics include the residual standard error, the coefficient of determination (R2 and "adjusted" R2), the F-statistic for the overall model with its numerator and denominator degrees of freedom, and standard errors, t-statistics, and finally corresponding (two-sided) p-values for the model parameters.
