Consistent model selection in segmented line regression [PDF]

open access: yesJournal of Statistical Planning and Inference, 2016
The Schwarz criterion or Bayes Information Criterion (BIC) is often used to select a model dimension, and some variations of the BIC have been proposed in the context of change-point problems. In this paper, we consider a segmented line regression model with an unknown number of change-points and study asymptotic properties of Schwarz type criteria in ...

The Log Likelihood Ratio in Segmented Regression

open access: yesAnnals of Statistics, 1975
This paper deals with the asymptotic distribution of the log likelihood ratio statistic in regression models which have different analytical forms in different regions of the domain of the independent variable. It is shown that under suitable identifiability conditions, the asymptotic chi square results of Wilks and Chernoff are applicable. It is shown

Optimal Segmented Linear Regression for Financial Time Series Segmentation [PDF]

open access: yes2021 International Conference on Data Mining Workshops (ICDMW), 2021
Given a financial time series data, one of the most fundamental and interesting challenges is the need to learn the stock dynamics signals in a financial time series data. A good example is to represent the time series in line segments which is often used as a pre-processing step for learning marketing signal patterns in financial computing.

Multiatlas Segmentation as Nonparametric Regression [PDF]

open access: yesIEEE Transactions on Medical Imaging, 2014
This paper proposes a novel theoretical framework to model and analyze the statistical characteristics of a wide range of segmentation methods that incorporate a database of label maps or atlases; such methods are termed as label fusion or multiatlas segmentation.
