On measures of explained variance in nonrecursive structural equation models.
Whereas measures of explained variance in a regression and an equation of a recursive structural equation model can be simply summarized by a standard R2 measure, this is not possible in nonrecursive models in which there are reciprocal interdependencies among variables. This article provides a general approach to defining variance explained in latent dependent variables of nonrecursive linear ...
متن کاملPhenotypic variance explained by local ancestry in admixed African Americans
We surveyed 26 quantitative traits and disease outcomes to understand the proportion of phenotypic variance explained by local ancestry in admixed African Americans. After inferring local ancestry as the number of African-ancestry chromosomes at hundreds of thousands of genotyped loci across all autosomes, we used a linear mixed effects model to estimate the variance explained by local ancestry...
متن کاملVariance Explained: Why Size Does Not (Always) Matter
I examine the role of explaining variance in the construction of explanatory theory. Explaining variance can be an insufficient basis for evaluating a theory (Lieberson, 1985). Starting with this insight, I suggest that models that provide explanations of variance do not necessarily provide good explanations of causal mechanisms. I then explore the utility of process models and theories (Mohr, ...
متن کاملUsing Explained Variance Allocation to analyse Importance of Predictors
Using applications of linear regression, Market Research practitioners want to determine a ranking of predictors or a quantification of their respective importance for a desired outcome. As predictors are often correlated, regression coefficients can be difficult to use directly because they can be instable across samples and have negative values that are counterintuitive. To overcome these dif...
متن کاملComments on relaxed $(gamma, r)$-cocoercive mappings
We show that the variational inequality $VI(C,A)$ has aunique solution for a relaxed $(gamma , r)$-cocoercive,$mu$-Lipschitzian mapping $A: Cto H$ with $r>gamma mu^2$, where$C$ is a nonempty closed convex subset of a Hilbert space $H$. Fromthis result, it can be derived that, for example, the recentalgorithms given in the references of this paper, despite theirbecoming more complicated, are not...
