This article details initial measure development, exploratory factor analysis, and preliminary validation of the Gay Community Involvement Index (GCII) across two studies. Previous research on gay community involvement has relied on measures that do not distinguish between distinct ways in which men may...
The main difference between these two models is that the component model assumes no measurement error and the common factor model attempts to account for measurement error. Principal component analysis (PCA) is one of the more frequently used component model–based factor extraction methods for EFA....
There have been numerous studies employing statistical tools, such as factor analysis/PCA for the isolation of different dimensions in exploratory behavior. They either used this statistical approach for a single task33,34,35,36 or collapsed the analyses over multiple test situations27,37,38,39,40...
PCA: DA-Principal component analysis-based discriminant analysis PBT: Parenchymal brain tumor BM: Brain metastasis BT: Primary brain tumor HC: healthy control HRMS: high-resolution mass spectrometry TME: tumor microenvironment ID: Inflammatory disease PC: Phosphatidylcholines AC: Acylcarnitine...
To reduce the dimensionality of the scRNA-seq dataset, principal component analysis (PCA) was performed using the top 2000 highly variable genes. The Elbowplot function of the Seurat package was utilized to select the top 20 principal components (PCs) for downstream analysis. ...

This paper applies PCA first for the full sample, then, as a robustness check, to the different periods established in the VAR analysis. PCA provides a broad view of the connections among the studied assets and allows us to estimate a factor underlying the movements of these financial instrumen...
