401-0627-00L  Smoothing and Nonparametric Regression with Examples

SemesterHerbstsemester 2019
DozierendeS. Beran-Ghosh
Periodizitätjährlich wiederkehrende Veranstaltung

KurzbeschreibungStarting with an overview of selected results from parametric inference, kernel smoothing will be introduced along with some asymptotic theory, optimal bandwidth selection, data driven algorithms and some special topics. Examples from environmental research will be used for motivation, but the methods will also be applicable elsewhere.
LernzielThe students will learn about methods of kernel smoothing and application of concepts to data. The aim will be to build sufficient interest in the topic and intuition as well as the ability to implement the methods to various different datasets.
InhaltRough Outline:

- Parametric estimation methods: selection of important results
o Maximum likelihood, Method of Least squares: regression & diagnostics

- Nonparametric curve estimation
o Density estimation, Kernel regression, Local polynomials, Bandwidth selection
o Selection of special topics (as time permits, we will cover as many topics as possible) such as rapid change points, mode estimation, robust smoothing, partial linear models, etc.

- Applications: potential areas of applications will be discussed such as, change assessment, trend and surface estimation, probability and quantile curve estimation, and others.
SkriptBrief summaries or outlines of some of the lecture material will be posted at https://www.wsl.ch/en/employees/ghosh.html.

NOTE: The posted notes will tend to be just sketches whereas only the in-class lessons will contain complete information.
