Ordinal Log-Linear Models for Contingency Tables

open access: yesFolia Oeconomica Stetinensia, 2016
A log-linear analysis is a method providing a comprehensive scheme to describe the association for categorical variables in a contingency table. The log-linear model specifies how the expected counts depend on the levels of the categorical variables for ...

ESTUDIO DE ASOCIACIÓN ENTRE DROSOPHILA Y LEVADURAS USANDO EL ANÁLISIS DE DEPENDENCIA

open access: yesPesquimat, 2014
In this paper, we present the metodology of the Analysis of Dependence (ANADEP) for suggested contingency tables developed by Cordeiro (1990), using the association measures M, in the study ofstructure of association in bidimensional contingency tables.

Accurate and Efficient Private Release of Datacubes and Contingency Tables [PDF]

open access: yes, 2012
A central problem in releasing aggregate information about sensitive data is to do so accurately while providing a privacy guarantee on the output. Recent work focuses on the class of linear queries, which include basic counting queries, data cubes, and ...

Markov chain Monte Carlo tests for designed experiments

open access: yes, 2006
We consider conditional exact tests of factor effects in designed experiments for discrete response variables. Similarly to the analysis of contingency tables, a Markov chain Monte Carlo method can be used for performing exact tests, when large-sample ...

Transforming Contingency Tables

open access: yesThe Annals of Statistics, 1982
Abstract : We present a general theorem on transforming contingency tables and several applications where the transformation technique has allowed us to take advantage of the Iterative Proportional Fitting Procedure and has resulted in simple and useful procedures.

Markov bases and subbases for bounded contingency tables

open access: yes, 2010
In this paper we study the computation of Markov bases for contingency tables whose cell entries have an upper bound. In general a Markov basis for unbounded contingency table under a certain model differs from a Markov basis for bounded tables. Rapallo,

A Guide to CoCo

open access: yesJournal of Statistical Software, 2001
CoCo is a program for estimation, test and model search among hierarchical interaction models for large complete contingency tables. The name CoCo is derivated of "Co"mplete "Co"ntingency tables, since the initial program could only handle complete ...

The Geometry of Statistical Models for Two-Way Contingency Tables with Fixed Odds Ratios [PDF]

open access: yes, 2005
We study the geometric structure of the statistical models for two-by-two contingency tables. One or two odds ratios are fixed and the corresponding models are shown to be a portion of a ruled quadratic surface or a segment.

Infinite factorization of multiple non-parametric views [PDF]

open access: yes, 2010
Combined analysis of multiple data sources has increasing application interest, in particular for distinguishing shared and source-specific aspects. We extend this rationale of classical canonical correlation analysis into a flexible, generative and non ...

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
