Visual Analytics for Development and Evaluation of Order Selection Criteria for Autoregressive Processes
IEEE Transactions on Visualization and Computer Graphics
|November 4, 2015
Summary
We introduce a visual analytics tool to help experts develop and evaluate automatic order selection criteria for autoregressive processes. This approach enables faster, real-time, feedback-driven development of time series analysis methods.
Area of Science:
- Statistics
- Computer Science
- Data Visualization
Background:
- Order selection for autoregressive processes is crucial but challenging for domain experts.
- Developing and evaluating automatic order selection criteria requires significant effort.
Purpose of the Study:
- To propose a visual analytics approach to guide the development and evaluation of automatic order selection criteria.
- To facilitate real-time, feedback-driven development and fine-tuning of these criteria.
Main Methods:
- A flexible synthetic model generator combined with specialized responsive visualizations.
- Interactive evaluation framework for comprehensive analysis.
Main Results:
- Demonstrated applicability in three use-cases, including general and real-world examples.
- Enabled fast, feedback-driven development and real-time fine-tuning of order selection criteria.
Conclusions:
- The visual analytics approach effectively supports the development and evaluation of autoregressive process order selection criteria.
- The framework accelerates the creation and refinement of time series analysis tools.

Regression Analysis
8.9K
Regression analysis is a statistical tool that describes a mathematical relationship between a dependent variable and one or more independent variables.
In regression analysis, a regression equation is determined based on the line of best fit– a line that best fits the data points plotted in a graph. This line is also called the regression line. The algebraic equation for the regression line is called the regression equation. It is represented as:

Econometric Views (EViews)
676
Econometric Views, often stylized as EViews, is a package that merges statistical analysis with econometric studies. It is designed to provide tools for time series analysis, forecasting, and econometric model simulation. The software originated from MicroTSP software and has evolved significantly since its inception in 1981. The history of EViews is marked by a continuous effort to enhance its computational speed and user interface. It was initially developed for large computing systems but...

Statistical Analysis: Overview
17.2K
When we take repeated measurements on the same or replicated samples, we will observe inconsistencies in the magnitude. These inconsistencies are called errors. To categorize and characterize these results and their errors, the researcher can use statistical analysis to determine the quality of the measurements and/or suitability of the methods.
One of the most commonly used statistical quantifiers is the mean, which is the ratio between the sum of the numerical values of all results and the...

Response Surface Methodology (RSM) is a collection of statistical and mathematical techniques used to develop, improve, and optimize processes. It is particularly valuable when many input variables or factors potentially influence a response variable.
The process of RSM involves several key steps:

Friedman Two-way Analysis of Variance by Ranks
567
Friedman's Two-Way Analysis of Variance by Ranks is a nonparametric test designed to identify differences across multiple test attempts when traditional assumptions of normality and equal variances do not apply. Unlike conventional ANOVA, which requires normally distributed data with equal variances, Friedman's test is ideal for ordinal or non-normally distributed data, making it particularly useful for analyzing dependent samples, such as matched subjects over time or repeated measures...

Introduction To Survival Analysis
963
Survival analysis is a statistical method used to study time-to-event data, where the "event" might represent outcomes like death, disease relapse, system failure, or recovery. A unique feature of survival data is censoring, which occurs when the event of interest has not been observed for some individuals during the study period. This requires specialized techniques to handle incomplete data effectively.
The primary goal of survival analysis is to estimate survival time—the time...
