forecast vs fable comparison #7

Open emitanaka opened 3 years ago

@Yiwen-Zhang-259 when you get a chance could you have a look also at the download logs for fable and forecast. I know (at least for a subset of CRAN packages), older packages generally have more download (like say in the last two years) than newer packages (you can plot "total downloads over last 2 years" vs. "Date when package got released" to explore this). I suspect though that the rate of recent download is quite different for these with fable getting far more download in recent times. Note that pkgsearch:: cran_trending can find trending packages. This information might be more interesting than looking at total downloads and be an alternative indicator of how impactful a package is.

Oh, after ploting, I found that fable is older than forecast (by checking the published date from CRAN website), but the download count of forecast is much more than that of fable in last two years.

Yup I know. fable is the tidy version of forecast and got on CRAN only recently. You shouldn't compare the raw download counts directly since it's natural that forecast will have much higher download. What about the rate of download? Look into pkgsearch::cran_trending if you need some inspiration to think of different ways of comparing.
