Common and Cluster-Specific Simultaneous Component Analysis
In many fields of research, so-called 'multiblock' data are collected, i.e., data containing multivariate observations that are nested within higher-level research units (e.g., inhabitants of different countries). Each higher-level unit (e.g., country) then corresponds to a 'data block'. For such data, it may be interesting to investigate the extent to which the correlation structure of the var...
متن کاملCorrection: Common and Cluster-Specific Simultaneous Component Analysis
In the Methods section, there are errors in the first and second equation in the section titled "2.2. CC-SCA-ECP Model." The publisher apologizes for these errors. The second line after the first equation incorrectly describes the Equal Cross Product (ECP) constraints. The correct equation is:
متن کاملSimultaneous component and cluster analysis: the between and the within approaches
A relevant methodology to summarize three-way data is three-mode factor analysis (T3) (Tucker, 1966) where units, variables and occasions are reduced into a small number of components. Although in multivariate analyses variables and occasions are often summarized by factorial methodologies, units are more frequently partitioned into a few homogeneous classes by a clustering technique. This can ...
متن کاملCommon factor analysis versus principal component analysis: choice for symptom cluster research.
PURPOSE The purpose of this paper is to examine differences between two factor analytical methods and their relevance for symptom cluster research: common factor analysis (CFA) versus principal component analysis (PCA). METHODS Literature was critically reviewed to elucidate the differences between CFA and PCA. A secondary analysis (N = 84) was utilized to show the actual result differences f...
متن کاملA clusterwise simultaneous component method for capturing within-cluster differences in component variances and correlations.
This paper presents a clusterwise simultaneous component analysis for tracing structural differences and similarities between data of different groups of subjects. This model partitions the groups into a number of clusters according to the covariance structure of the data of each group and performs a simultaneous component analysis with invariant pattern restrictions (SCA-P) for each cluster. T...
