Linear structural equations with latent variables
Peter M. Bentler,David G. Weeks +1 more
TL;DR: In this article, an interdependent multivariate linear relations model based on manifest, measured variables as well as unmeasured and unmeasurable latent variables is developed, which is designed to accommodate a wider range of applications via its structural equations, mean structure, covariance structure, and constraints on parameters.
Journal ArticleDOI
Relation between loneliness and depression: a structural equation analysis.
TL;DR: Loneliness and depression were correlated but clearly different constructs; neither was a direct cause of the other, though both probably share some common origins; both were highly stable over to 5-week-period.
Journal ArticleDOI
Perceived dimensions of attributions for loneliness.
TL;DR: Confirmation of Internality and Stability as dimensions underlying attributions for loneliness supported the extension of Weiner's model to the domain of affiliative behavior.
Journal ArticleDOI
Acid resistance of Helicobacter pylori depends on the UreI membrane protein and an inner membrane proton barrier
Marina Rektorschek,Anita Buhmann,David G. Weeks,Dorothee Schwan,Klaus W. Bensch,Sepehr Eskandari,David Scott,George Sachs,Klaus Melchers +8 more
TL;DR: The role of the bacterial inner membrane and ureI in acid protection and regulation of cytoplasmic urease activity in the gastric microorganism was studied in this article.
Journal ArticleDOI
Restricted multidimensional scaling models
Peter M. Bentler,David G. Weeks +1 more
TL;DR: In this paper, a class of multidimensional scaling models are developed wherein certain parameters may be fixed as known constants, or proportional to one another, and methods of obtaining least square estimates of the parameters via nonlinear programming are discussed, and an effective computer program is developed to implement application of the models to data.
