Regularized Ordinal Regression and the ordinalNet R Package

open access: yes, 2017
Regularization techniques such as the lasso (Tibshirani 1996) and elastic net (Zou and Hastie 2005) can be used to improve regression model coefficient estimation and prediction accuracy, as well as to perform variable selection.

Penerapan Metode Suksesif Interval pada Analsis Regresi Linier Berganda

open access: yesJambura Journal of Mathematics, 2019
Dalam menggunakan model regresi linier disyaratkan data yang digunakan hendaknya berskala interval atau rasio. Akan tetapi jika skala dalam bentuk ordinal tetap dipaksakan menggunakan model regresi linier, maka akan diperoleh koefisien korelasi yang ...

Comparison of Ordinal Response Modeling Methods like Decision Trees, Ordinal Forest and L1 Penalized Continuation Ratio Regression in High Dimensional Data

open access: yesIranian South Medical Journal, 2021
Background: Response variables in most medical and health-related research have an ordinal nature. Conventional modeling methods assume predictor variables to be independent, and consider a large number of samples (n) compared to the number of covariates

Ordinal Patterns, Entropy, and EEG

open access: yesEntropy, 2014
In this paper we illustrate the potential of ordinal-patterns-based methods for analysis of real-world data and, especially, of electroencephalogram (EEG) data. We apply already known (empirical permutation entropy, ordinal pattern distributions) and new

Estimation from Pairwise Comparisons: Sharp Minimax Bounds with Topology Dependence [PDF]

open access: yes, 2015
Data in the form of pairwise comparisons arises in many domains, including preference elicitation, sporting competitions, and peer grading among others. We consider parametric ordinal models for such pairwise comparison data involving a latent vector $w^*

The Assignment of Scores Procedure for Ordinal Categorical Data

open access: yesThe Scientific World Journal, 2014
Ordinal data are the most frequently encountered type of data in the social sciences. Many statistical methods can be used to process such data. One common method is to assign scores to the data, convert them into interval data, and further perform ...
