A new nonparametric regression technique is proposed which involves the extension of local polynomial fitting to the empirical likelihood context, where the ...
The kernel estimator fits a local mean at each point x and thus cannot even estimate a line without bias (Cleveland, Cleveland, Devlin and Grosse 1988). An estimator based on locally-weighted ...
Figure 39.39 displays a quadratic polynomial fit with 95% mean confidence curves for the response. Use the Coefficient slider to change the confidence coefficient. Figure 39.39: A Quadratic Polynomial ...
