comment What happens if I toss a coin with decreasing probability to get a head?
Hi @AndréNicolas, I think I am missing something. The limit of $$ (2^n - 1) / 2^n $$ when n -> ∞ is ∞, isn't it?

comment Why there aren't any squares of 2 divisible by 3?
I am afraid I do not get this. You divide your cake in four pieces, fine. You give one pieces to each person, then you divide the remaining piece into four. Now, if you give one of these sub-pieces to each person, you remain with one sub-piece. Am I missing something?

Six in an even number; if you double it, you get twelve. Both are divisible by three.

Thank you for the clarification. I corrected the post, as I intended "repeating decimal" and not "irrational". Now it should make sense.

comment Weird formula for linear regression
I may have missed something but how can I minimize the error if I do not have the data I am trying to predict? Or should I find the parameters on the basis of the data I do have? One addition: on the report I found a footnote saying "parameters d and α are found with estimation techniques". Does this one add some extra useful information?

@ClaudeLeibovici I am afraid I did not understand the request. By the way, T stands for time (in this context, days).

@ClaudeLeibovici No formula, those are real data.
