PCA is performed on the permuted matrix to obtain the percentage of variance explained under a random null hypothesis. This is repeated over several iterations to obtain a distribution of curves on the scree plot.Details. paran is an implementation of Horn's (1965) technique for evaluating the components or factors retained in a principle component analysis (PCA) or common factor analysis (FA).According to Horn, a common interpretation of non-correlated data is that they are perfectly non-colinear, and one would expect therefore to see eigenvalues equal to 1 in a PCA (or 0 in an FA) of such random data.The Lanczos eigensolver uses thread-based parallelization; therefore, parallel execution of the Lanczos eigensolver is available only on shared memory computers. The number of solver threads is equal to the number of processors used for the analysis. Parallel execution of element operations is not supported with the Lanczos eigensolver.Parallel Computing Toolbox enables you to harness a multicore computer, GPU, cluster, grid, or cloud to solve computationally and data-intensive problems.
