WebNov 23, 2024 · 1 Answer. Sorted by: 1. I don't see any special value to averaging coefficients of variation (CVs). Ideally your CV is consistent across datasets or groups or variables in which case you can underline that fact by citing a narrow range. Conversely, if your CV is not at all consistent an average is not informative and how to get it a secondary ... WebJan 9, 2024 · For sizable deployments, the incremental cost of RDS infrastructure VMs will average out to $1 to $2 per user/month making the true cost AVD and RDS about the same. In small deployments (<25 users), where there aren’t enough users to amortize the cost of RDS infrastructure VMs across, RDS will be slightly more expensive.
