It seems that var() computes sample variance. It is straight forward to compute population variance from sample variance. However, I feel that it is still convenient to have a function that can compute population variance. Is there a population variance function available in R?
$ Rscript var.R > set.seed(0) > n = 4 > x = rnorm(n) > var(x) [1] 0.6526278 > sum((x-mean(x))^2)/(n-1) [1] 0.6526278 > ______________________________________________ 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.
