Groupmeans = as.matrix(by(x$value,x$group,mean));. Goriely show that, in estimating the number of eigenvectors which are of statistical significance in the PCA analysis of DNA microarray data, the method of cumulative percent of variance should not be used. Power analysis is a very useful tool to estimate the statistical power from a study. Prior knowledge of multilevel analysis is not required, but a basic knowledge of regression analysis , (asymptotic) statistics, and matrix algebra is assumed. Power Analysis and the Probability of Errors. Statistical Science, 11, 20-34. A summary of the For example, R. Fisher and multivariate analysis. The modification incorporates a test for the presence of an "effective degeneracy" among the subspaces spanned by the eigenvectors of the correlation matrix of the data set then allocates the total variance among subspaces. Again, this is a bit different from “old school” multivariate statistics (which reminds me, John Marden has produced a great text available freely on-line on old school multivariate analysis, which isn't quite as “old school” as the title might suggest). As I was exploring the Spatial Statistics Resources web-page, I quickly realized most of the spatial statistical tools offered by ESRI are not applicable to my project. Modeling covariance matrices in terms of standard deviations and correlations, with application to shrinkage.
