Degenerate Function/Polynomial: A generalised function or polynomial in which a parameter is introduced to modify its standard form, thereby unifying or extending classical results.

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 ...

Zernike and Legendre polynomials are different parameterizations of regular XY Cartesian polynomials commonly used to model overlay, based on combinations of standard terms. Zernike polynomials are ...
