why the inverse of geo would be expected value of indicatpr variable?
I'm sure this is a basic question, but why is E[Xi] the inverse of the geometric distribution? Around 4:50
Great presentation, thanks. Minor typo at the end (6:46) the last sum is from 1 to K (as opposed to K-1).
Very helpful.. :+1:
What a God awful presentation!
1- For grades collection to qualify as a coupon collector problem, you should make it clear that the grades are uniformly distributed, which you didn't, and that the papers are being replaced back into the stack, which you also missed.
2- What on earth is Xi = Geo(6-x/6)? Xi is a random variable who's probability distribution is geometric not the variable itself!
3- You should've hinted at "n-th Harmonic" when you got stuck evaluating that God awful summation at the end since the entire problem can be reduced to n*Hn ;-).
what is the coupons collector problem?
i dont want to be the only critic but i guess i learn different and i learn through the asking of why per step.. this video is very difficult to chew
Very helpful and clear! Thanks a lot!
id stick with coupons instead of grades in the description, grades linguistically have an implication of non-randomness. It subtly makes it harder to imagine the probability of getting a 'random' grade
Thank you! I have a midterm later today and could not understand this very well. Kudos to you!
thanks for the great video. isn't there a small mistake at the end? the last but one expression should read k, sum i = 1 to k, 1 over i ?
