 Jan12 awarded Curious Jan9 awarded Commentator Jan9 comment Find the point where the slope changes drastically @coffeemath it seems your right! I found this one, it seems the OP is asking for the same thing but I can't make sense out of the answer. Jan9 comment Find the point where the slope changes drastically @user86418, I understand your point. :( I think it would correct to call it an inflection points, but I am not 100% sure. Jan9 asked Find the point where the slope changes drastically Mar7 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? Mar6 asked What happens if I toss a coin with decreasing probability to get a head? Feb22 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? Feb22 comment Why there aren't any squares of 2 divisible by 3? Six in an even number; if you double it, you get twelve. Both are divisible by three. Feb22 awarded Supporter Feb22 comment Why there aren't any squares of 2 divisible by 3? Thank you for the clarification. I corrected the post, as I intended "repeating decimal" and not "irrational". Now it should make sense. Feb22 comment Why there aren't any squares of 2 divisible by 3? Sorry, oversights. I corrected everything. Feb22 asked Why there aren't any squares of 2 divisible by 3? Jan28 asked Using mutual information to estimate correlation between a continuous variable and a categorical variable Jan25 awarded Scholar Jan25 accepted Is Standard Deviation the same as Entropy? Jan25 answered If three groups of unequal sizes have the same standard deviation but different means, will the SD of the pooled data be the same? Jan25 asked Is Standard Deviation the same as Entropy? Nov11 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? Nov11 comment Weird formula for linear regression @ClaudeLeibovici I am afraid I did not understand the request. By the way, T stands for time (in this context, days).
