PowerTOST usage [🇷 for BE/BA]
Dear All!
This post is a little bit off topic.
As the developer of the PowerTOST package I'm naturally interested in the question "Who (how many and from where) uses this package". Normally one can't get an answer to this question since CRAN has many mirrors and therefore a download statistic is impossible to get.
But thanks to the people developing RStudio there are now log-files of their CRAN cloud which can be used for an answer. See f.i. this blog.
I found the results interesting enough to share.
For others then me the question above translates to: "Where are people sitting around in the world who have need of power calculations / sample size estimation for bioequivalence studies and are using R for that end?".
Here the results for the three last PowerTOST versions (omitting orphans with only one download of any PowerTOST version):
Downloads via rstudio.com from 2013-06-21 to 2014-02-01.
(release of V1.1-06 to release of V1.1-10, V1.1-09 not released to the public)
This is naturally only one piece of the picture since it requires that the R-User also use CRAN.RStudio.com for downloading their packages. And downloading is not usage.
V1.1-08 is only 5 weeks old so users which infrequently updating their package use V1.1-07 yet. But V1.1-08 is now already outdated since V1.1-10 is on the way.
But interesting, isn't it
?
Some countries I hadn't expected at all!
Others surprised me with high usage (JP, US, VN) and f.i. our Indian friends with low usage in respect to the high numbers of Forum users.
