Coin flipping head, tail or edge
On 28, Jan I changed the sample space for a coin flip to 3 = head, tail, edge. My source is a paper issued in 1993 in the Physical Review a scientific journal. The authors were Daniel B. Murray and Scott W. Teare. So far no one seems to bother my contribution. I guess it make sense, I should change all related articels in the follwoing weeks e.g. Sample Space. I got the article as a pdf file. Any comments for this?

- That paper doesn't show it's possible that a coin lands on its edge as the authors don't say they observed a coin landing on its edge even once, only what "extrapolations based on the model suggest...". As a statistician, I'm naturally skeptical about using a model based to extrapolate beyond the range of observed data as all models are wrong. Sure, I believe it might be possible, but I've never observed it myself, and this paper doesn't demonstrate it is possible, it only reports the probability that their models suggests. --Qwfp (talk) 20:28, 31 January 2019 (UTC)
Cluster Analysis page edited by SPA
The Cluster Analysis page is being overedited/overhauled by a special purpose account Glokc (talk · contribs · deleted contribs · logs · filter log · block user · block log). It deserves a look and some scrutiny . Limit-theorem (talk) 18:03, 2 February 2019 (UTC)
- The Cluster Analysis page has been extended by me and all the made statements have references to the state-of-the-art scientific papers published in the peer reviewed journals and conferences. I have not deleted any of the original material, just restructured it a bit, significantly extended and modified some statements (citing the trusted scientific papers). I believe that the article has been improved with the made changes and would be glad to receive some feedback and refinements for the made edits but the account Limit-theorem (talk · contribs · deleted contribs · logs · filter log · block user · block log) just "undo"-ed my extensions multiple times instead of refining them further. --Glokc (talk) 18:18, 2 February 2019 (UTC)
WikiProject Data Science
There's an upstart WikiProject for data science. It doesn't look very active anymore, but I suggested merging them into Statistics or CS as a task force. Qzekrom (talk) 22:33, 9 February 2019 (UTC)
