Income-Well-Being Gradient in Sickness and Health. [PDF]

open access: yesHealth Econ
ABSTRACT We propose a method for studying the value of insurance. For this purpose, we analyze the well‐being of the same individuals, comparing sick and healthy years, using German panel survey data on life satisfaction. We impose structure on the income–well‐being gradient by fitting a flexible utility function to the data, focusing on the ...

Fission-Fusion Group Dynamics and Cooperative Hunting Stabilise Social Carnivore Populations. [PDF]

open access: yesEcol Lett
Fission‐fusion subgroup dynamics within prides allows lions to alleviate the foraging cost of sociality. This has the effect of both stabilising ecological interactions with their prey as well as allowing large prides to persist, features of the Serengeti ecosystem that have long eluded researchers.

The Association of Periodontitis and Stroke History: Exploring the Role of Hypertension in a Cross-Sectional NHANES Analysis. [PDF]

open access: yesInt J Dent
Background Periodontitis, a chronic inflammatory disease, and stroke, a leading cause of death and disability, share common risk factors and inflammatory pathways. However, the role of key mediators such as hypertension in this relationship remains to be fully elucidated.

Restricted graphical log-linear models

open access: yesAustrian Journal of Statistics, 2015
We introduce a new type of graphical log-linear model called restricted graphical log-linear model. This model is obtained by imposing equality restrictions on subsets of main effects and of first-order interactions.

Rest-Activity Rhythms and Suicidal Ideation in Pediatric Bipolar Disorder. [PDF]

open access: yesBipolar Disord
ABSTRACT Introduction Risk for suicide is disproportionately elevated among youth with bipolar spectrum disorder (BD), which is characterized by recurrent mood episodes and significant shifts in sleep and circadian rhythm. Disruptions in circadian rhythm, such as 24‐h rest‐activity patterns, are a relevant risk factor for SI, yet understudied in BD ...

Underlying Distributions in Loglinear Models of Discrete Data [PDF]

open access: yes, 2012
The implications of loglinear models based on underlying uniform and binomial distribution are assessed with respect to modeling eight distributions. Regarding statistical selection of the loglinear models’ parameterizations, results indicate that better

The Use of Loglinear Models for Assessing Differential Item Functioning Across Manifest and Latent Examinee Groups [PDF]

open access: yes, 1990
Loglinear latent class models are used to detect differential item functioning (DIF). These models are formulated in such a manner that the attribute to be assessed may be continuous, as in a Rasch model, or categorical, as in Latent Class Mastery models.

Exact Hypothesis Tests for Log-linear Models with exactLoglinTest

open access: yesJournal of Statistical Software, 2006
This manuscript overviews exact testing of goodness of fit for log-linear models using the R package exactLoglinTest. This package evaluates model fit for Poisson log-linear models by conditioning on minimal sufficient statistics to remove nuisance ...

Loglinear Rasch Model Tests [PDF]

open access: yesPsychometrika, 1984
Existing statistical tests for the fit of the Rasch model have been criticized, because they are only sensitive to specific violations of its assumptions. Contingency table methods using loglinear models have been used to test various psychometric models.

Assessment of synchrony in multiple neural spike trains using loglinear point process models [PDF]

open access: yes, 2011
Neural spike trains, which are sequences of very brief jumps in voltage across the cell membrane, were one of the motivating applications for the development of point process methodology.
