Data comparison using Gaussian Graphical Models

2014 12th International Conference on Signal Processing (ICSP), 2014
This paper focuses on estimated Gaussian Graphical Models (GGM) from sets of experimental data. Some extension of known Bayesian methods are proposed, allowing to introduce score functions to measure the relevance of the obtained GGM structure to describe the data.

Graphic comparisons of interobserver agreement indices

Journal of Psychopathology and Behavioral Assessment, 1990
How changes in the interobserver agreement and disagreement cells in the reliability matrix are reflected differently in eight commonly used reliability indices is shown graphically. Indices which take into account expected chance difference are compared to those indices which do not.

Graphic Comparisons of Meristic Data

Copeia, 1963
Graphic comparisons of meristic data are discussed. The usual presentation of graphic analysis is similar to the form proposed by Hubbs and Perlmutter. Methods of presentation may be uncritical and the procedure itself is subject to inherent statistical weaknesses.

Comparison of microprocessors: a graphical approach

Euromicro Newsletter, 1977
Abstract Selecting a microprocessor for a particular application is a task frequently faced today. Manufacturers usually present hardware characteristics consistently, but vary considerably in the way they describe instruction sets, which makes microprocessor comparison tedious and time-consuming.

Graphic comparison of three-state device redundancies

Microelectronics Reliability, 1984
Abstract The reliabilities of a single three-state device, a system composed of two such devices in series, and that in parallel are compared directly and their respective optimal regions are shown graphically.

Graphical factor analysis models: specification and model comparison

1998
We introduce a graphical factor analysis model as a graphical Gaussian model with latent variables satisfying a set of conditional independence constraints. After a brief introduction of the factor analysis model, we generalise the class of such models by allowing the concentration matrix of the residuals to have non-zero off-diagonal elements.

Comparison of Graphical Passwords Using ISO 9126

Advanced Science Letters, 2018
This article is to learn the characteristics of graphical passwords by comparing different categories of graphical passwords with the ISO 9126 model. The ISO 9126 model is divided into six parts, which are usability, reliability, functionality, maintainability, efficiency, and portability. Each part listed is sub-categorised by the standard and is used

Graphical Representations of Tukey's Multiple Comparison Method

Journal of Computational and Graphical Statistics, 1994
Abstract Tukey's multiple comparison method is widely implemented in statistical packages. We list the inferential and perceptual tasks a graphical representation of Tukey's method may be required to perform, and show that the most commonly used graphical representations (underlining, line-by-line plotting, notched boxplots, and comparison circles) are

Storage Tube Graphics a Comparison of Terminals

1971
There is a growing demand for low cost computer graphics for the small scale computer user or for the user who would rather have easy access to a somewhat less sophisticated console than have very limited access (a few hours per day or even a week) to a more powerful but far more expensive device. The possibility of obtaining a work station with random
