    Let pi = P(Ti > t) 0

      Thanks, IppolitoMath, for adding that. It's a subtlety that I should have discussed more in the video. The correction of a/n is the upper bound of the p-value assuming independence.

      @@mikexcohen1 Thank you, I misspoke I didn't mean "independence" I meant "disjoint". The probability of a finite union of sets is bounded by them sum of the probability of events, and equal when the sets are disjoint. The sets in this case are the events that a p-value is greater than alpha under the null hypothesis.
      I've not see disjoint mentioned with regards to Bonferroni before.

    Awesome Video. How about the False Discovery Rate (FDR) Method that is a new approach to multiple comparisons?

      Yes, FDR is also possible, but it doesn't provide cluster-level corrections that are useful for spatiotemporally correlated data, which I discuss in later videos.

    I don't believe Bonferroni assumes independence, but bounds the Type I family rate for a particular set of comparisons which might be dependent by the special case of independence.
