The QR code for the Japanese one has been long released <| sep |> Fwiw when I was young I stayed an A cup until I was 19 ish , and then went up to B only because I got on the contraceptive pill . If you stick to a healthy diet and exercise routine don ' t overdo it ! tbh you should be okay <| sep |> I ' m not saying it ' s not a good book . But you have no idea what the basics are . You don ' t know not to apply a posterior to the same experiment ' s prior , you don ' t know the difference between mean and median , you don ' t know the definition of a freaking mean . I talk to you about variance , you go on about how only Gaussians have stdevs . To you , each distribution apparently has some magical specific expected value , you seem not to understand that it ' s all a result of simplifying the same Ex equation , based on the probability mass function . You recommending that book is like the Time Cube guy sending us to read a Brief History of Time . Honestly . You seem to have a basic idea of highlevel things , but a complete lack of fundamentals leads you to spout absolute nonsense . Trust me , I know these things . Start with the basics . Go read a Wikipedia article , or an introductory stats course . Or even Khan Academy , the guy is really good with the basics .
