Bernstein polynomial estimation provides a robust nonparametric technique for approximating both density and distribution functions. Based on the properties of Bernstein polynomials, which uniformly ...

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 ...

Chromatic symmetric functions and combinatorial polynomials are central constructs in modern algebraic combinatorics, extending classical graph invariants into rich algebraic frameworks. Originating ...

Abstract: Point spread function (PSF) characterizes the intensity distribution characteristics of each object point and is widely used in areas such as defocus estimation, non-blind image deblurring, ...

This is a preview. Log in through your library . Abstract After a hypothesis about some linear statistical model has been tested and rejected (e. g., in an ANOVA), many researchers employ the Scheffe ...

A new technique for determining what causes stem cells to convert into other cell types could revolutionize our understanding of how genes function. A fast and comprehensive method for determining the ...
