Hello, It might be a trivial question but I just wanted to find out the relationship between sdev and proportion of variance generated by prcomp. I got the following result from my data set
PC1 PC2 PC3 Standard deviation 104.89454 15.40910 9.012047 Proportion of Variance 0.52344 0.01130 0.003860 Cumulative Proportion 0.52344 0.53474 0.538600 first, I had thought that the variance must be standard deviation power to 2 but it seems that variance is sdev/200. Did I misunderstood some thing? Best, Carol ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
