Solving polynomials We solve polynomials algebraically in order to determine the roots - where a curve cuts the x -axis. A root of a polynomial function, f (x), is a value for x for which f (x) = 0.

The conditional variance function in a heteroscedastic, nonparametric regression model is estimated by linear smoothing of squared residuals. Attention is focused on local polynomial smoothers. Both ...
