Fast Kernel Smoothing in R with Applications to Projection Pursuit

open access: yesJournal of Statistical Software, 2022
This paper introduces the R package FKSUM, which offers fast and exact evaluation of univariate kernel smoothers. The main kernel computations are implemented in C++, and are wrapped in simple, intuitive and versatile R functions.

Asymptotics of Graphical Projection Pursuit

open access: yesThe Annals of Statistics, 1984
General conditions under which the asymptotic distribution of the almost all (with respect to the uniform measure on the unit ball of projecting vectors) projections is normal are given. Convergence in probability of empirical moments (of the first and second order) is also established.

Projection pursuit methods for exploratory supervised classification [PDF]

open access: yes, 2003
In high-dimensional data, one often seeks a few interesting low-dimensional projections which reveal important aspects of the data. Projection pursuit is a procedure for searching high-dimensional data for interesting low-dimensional projections via the ...

A Credit Rating Model for Enterprises Based on Projection Pursuit and K-Means Clustering Algorithm [PDF]

open access: yesJournal of Risk Analysis and Crisis Response (JRACR), 2012
This paper proposes a new credit rating model for enterprises based on the Projection Pursuit and K-means clustering algorithm. Firstly, using Projection Pursuit, the comprehensive credit score of each sample is obtained, so as to reflect the structure ...

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Interactive data exploration with targeted projection pursuit [PDF]

open access: yes, 2009
Data exploration is a vital, but little considered, part of the scientific process; but few visualisation tools can cope with truly complex data. Targeted Projection Pursuit (TPP) is an interactive data exploration technique that provides an intuitive ...
