CLV: Stata module to implement a clustering of variables around latent components

Statistical Software Components from Boston College Department of Economics

Abstract: clv clusters variables around latent components. The variables are clustered by searching to minimize at each step the decreasing of the T criterion computed as the sum of the first eigenvalues of the matrices of data of all the clusters. A hierarchical cluster analysis based on this criterion is realized. A consolidation procedure can be run in a second time, which allows assigning each variable to the more correlated latent components. The procedure is described by Vigneau and Qannari (Communications in Statistics - Simulation and Computation, 2003).
