E.g. if you are flipping a fair coin then p(h)=p(t) = 0.5 (k==2). The probability of observing some specific sequence htththhthtis just 0.5^m where here m = 10.
the probability of observing a single specific sequence is (1/k)^m.
@albertcardona hey, I'm waiting for you to assign me the eLife paper, so I can start to get reviewers!

“You can’t just be confident, you have to be confident about something.”
Research led by @jerlich and Xiaoyue Zhu in @nbdt_journal set out to disentangle the different kinds of confidence by designing a perceptual gambling task for rodents.

Elsevier/RELX profit rises 10%, investor call: "continuing to see strong growth" including from pay-to-read and pay-to-publish. From the www.journalology.com newsletter.
In my opinion, more researchers and universities need to stop supporting them. One way to help is to join the Free Journal Network https://fediscience.org/@alexh/114055607398246074

@adredish @pluralistic since online shopping is already dynamic it makes sense for stores to match. Probably you put items in your cart by scanning the QR code with your phone so that’s the price you get.

How does that "individual pricing in grocery stores" work? Does that mean the price can change from the time you take it off the shelf to the time you check out? How does that match the "economic agreement"? (which depends on full information on both sides).
At least airplane and online store prices lock in the individual price when you select it. It doesn't suddenly change at the payment page. Although, I'm sure that's the next enshitification step...
