Homophily‐adjusted social influence estimation

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Homophily and social influence are two key concepts of social network analysis. Distinguishing between these phenomena is difficult, and approaches to disambiguate the two have been primarily limited to longitudinal data analyses. In this study, we provide sufficient conditions for valid estimation of social influence through cross‐sectional ...

Lasso for hierarchical polynomial models

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract The divisibility conditions implicit in a polynomial hierarchy suggest parameter constraints in regression. With this idea, we establish strong and weak hierarchies for both the lasso and relaxed lasso. Our proposal extends prior work on hierarchical lasso, which was mainly concerned with models of degree 2.

Język współczesnej katechezy

open access: yesWrocławski Przegląd Teologiczny, 2012
Die sich des Wortes bedienende Katechese überliefert nicht nur das Wort, aber sie wartet auch eine Antwort. Die katechetische Sprache dient zur Anknüpfung einer persönlichen Relation mit Gott.

Sparse maximum likelihood estimation of regression models

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract For regression model selection and estimation, we study a small set of candidate models of maximum likelihood from which all information criteria such as the Akaike information criterion (AIC) and the Bayesian information criterion (BIC) choose their models.

Az elérhetőség és az idegenforgalom kapcsolata

open access: yesTér és Társadalom, 2009
Az idegenforgalom és a közúti elérhetőség közötti kapcsolat vizsgálata meglehetősen sok módszertani problémát vet fel. Bár a kapcsolat látszólag evidensnek tűnhet, mégis a statisztikai mérés meglehetősen nehéz.

Order restricted row‐column cluster randomized design

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract This research introduces a novel two‐stage cluster randomized design, the order restricted row‐column cluster randomized design. The new design builds upon the cluster randomized block design by incorporating a second layer of blocking, achieved through ranking cluster units that are randomly sampled from the population.

Mitigating measurement error in misspecified small area models

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract In the framework of Small area estimation, we consider an area‐level model where a subset of covariates is measured with error. The extent of the error is assumed to be constant throughout the areas, and it is expressed by a scalar parameter γ$$ \gamma $$, which multiplies the deterministic covariance matrix of the estimator of the true ...

Kísérlet egy régió szimulációs modelljének kidolgozására

open access: yesTér és Társadalom, 2007
A területi szerkezet és a területi folyamatok elemzésére korábban széles körben alkalmazott regionális input–output modellek fénykorát követően a területi kutatásokban is új elemzési eljárások jelennek meg.

Models as Documents, Documents as Models

open access: yes, 2022
In software engineering, documentation and models are both broad concepts which attract varying approaches and attitudes. Moreover, as the title indicates, they overlap: in some circumstances, an artefact thought of as a model can serve to document a software project, while in others, an artefact thought of as a document can be manipulated by model ...
