    One mistake: in Frequentist Inference, 95% confidence interval doesn't mean there is 95% chance the true value would fall into the interval, but if you repeat the estimation many times, there will be about 95% cases that the true value is indeed in the interval.

      Brilliant catch! I was about to call that out too. But really nice presentation. This guy clearly knows his stuff and has excellent clarity of thoughts.

      hey quick question, repeat many times, 95% cases in the interval, isn't that the empirical probability of 95%?

      @@GenzhPuff No the probability the point estimate is in the interval is either 0 or 1.
