Local Dependence and Guarding [PDF]

open access: yesCoRR, 2022
We study LFD, a base logic of functional dependence introduced by Baltag and van Benthem (2021) and its connections with the guarded fragment GF of first-order logic.

Constant Local Dependence

open access: yesJournal of Multivariate Analysis, 1998
The local dependence function is constant for the bivariate normal distribution. Here we identify all other distributions which also have constant local dependence. The key property is exponential family conditional distributions and a linear conditional

Local dependence in bivariate copulae with Beta marginals [PDF]

open access: yesRevista Colombiana de Estadística, 2017
The local dependence function (LDF) describes changes in the correlation structure of continuous bivariate random variables along their range. Bivariate density functions with Beta marginals can be used to model jointly a wide variety of data with ...

Dependence maps: Local dependence in practice

open access: yesStatistics and Computing, 2003
There is often more structure in the way two random variables are associated than a single scalar dependence measure, such as correlation, can reflect. Local dependence functions such as that of Holland and Wang (1987) are, therefore, useful. However, it

Are Exam Questions Known in Advance? Using Local Dependence to Detect Cheating. [PDF]

open access: yesPLoS ONE, 2016
Cheating is a common phenomenon in high stakes admission, licensing and university exams and threatens their validity. To detect if some exam questions had been affected by cheating, we simulated how data would look like if some test takers possessed ...

Joint Testlet Cognitive Diagnosis Modeling for Paired Local Item Dependence in Response Times and Response Accuracy

open access: yesFrontiers in Psychology, 2018
In joint models for item response times (RTs) and response accuracy (RA), local item dependence is composed of local RA dependence and local RT dependence. The two components are usually caused by the same common stimulus and emerge as pairs.

Scale dependence of local f(NL) [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2010
Byrnes C, Nurmi S, Tasinato G, Wands D. Scale dependence of local f(NL). JCAP. 2010;2010(02):034.We consider possible scale-dependence of the non-linearity parameter f(NL) in local and quasi-local models of non-Gaussian primordial density perturbations ...

Detecting local diversity-dependence in diversification [PDF]

open access: yesEvolution; international journal of organic evolution, 2018
Whether there are ecological limits to species diversification is a hotly debated topic. Molecular phylogenies show slowdowns in lineage accumulation, suggesting that speciation rates decline with increasing diversity. A maximum-likelihood (ML) method to
