By far the best video on this topic, the fact that you link this with other topics and not just focus on underfitting and overfitting in isolation is beautiful.

The birthday problem is always fun. Imagine that it was any r people. So the probability of no match then it would be P(no match)= [(365)(364) ... (365-r+1)]/365^r. Then the probability of at least 2 matches would be 1-P(no match)

@pensivenincompoop2016 2 ай бұрын

Extend this so that the minimum number of people is required to have a 50% probability that at least 2 people match.

This is a more straightforward method commonly used to solve this problem. Compare the max number found to the sum of all numbers, take the average, and double it. Then use the max of these two numbers. This method has some intuitive appeal. If the numbers are evenly distributed, the average would represent the midpoint, so doubling it could give a reasonable total estimate. I tested this out by solving a problem by estimating the highest number of houses on a street when we only knew a few of the house numbers on each street. I tested the tank method with the straightforward process, and the results were about the same.

@5:39 the average gap = sum of all gaps/n. But no matter at what nr you start if x1=24 and x2=29, then the gap between them is 29-24 = 5 not 4. you claim the second gap has size (x2-x1-1).

The content you made is really great but your speaking too fast and it sounds as if you are swallowing your words.....its a bit teasing as we have to pause and try to understand...may be you make the pronunciation more clearer. just my opinion, I dont know if others too felt it.

I have a question! I generally think of e as being fundamentally related to compounding growth, similarly to how pi is thought of as being fundamentally related to circles. So with that in mind, is there some important relationship between derangements and compounding growth? If there is, it isn't apparent to me.

I applaud you as a creative, but if you want a wider audience, you should make a conscious effort to speak slower and enunciate. I'm a pretty decent non-native english speaker and I had to focus way too much on deciphering what you were saying. I gave up before the end of the video.

@Braniac57 Жыл бұрын

I understand we have to round to the nearest integer because we can’t have a non integer amount of derangements. But i guess I’m a little confused on how we know for sure that rounding will result in the right answer

@phscience797 Жыл бұрын

Don‘t worry, that was not explained in the video. The reason is simply that the approximation 1 - 1/1! + 1/2! - 1/3! - … + (-1)^n/n! = 1/e is somewhat accurate. For when you plot the alternating behaviour of this sequence, you can see that if n is even, then as the next term added is negative, you are currently above the limit, and if n is odd, you are below the limit. But the next term has only size 1/(n+1)!, which is quite small. So we know that D_n = n! (1/e + r_n), where abs(r_n) <= 1/(n+1)!, so D_n = n!/e + n! r_n, and abs(n! r_n) <= 1/(n+1). So if n \geq 2, the approximation D_n = n! / e will be accurate to within less than 1/2. As you observed, D_n is an integer, which means precisely that we can conclude D_n = round(n! / e). For n = 0, n = 1, n = 2, we can check by hand that this formula works as well.

@astropgn Жыл бұрын

But why the limit goes to infinity and not to the total number of the population? Are we assuming the population is infinite? I would think that if the population has a finite size, the mean of the sample would get the true mean of the population as the sample size approaches the population size

(If u are a 3b1b reviewer, watch the video before reading my comment lol) I kinda got lost halfway through with all the math jargon 😅. First we were talking about hats and parties and then suddenly set intersections and permutations? The rest of the video seems to be mostly symbol manipulation and I think I'd understand it better if the actual math could be presented more closely to the context of the story. (I.e. talking about permutations of physical hats in a box, rather than items in a set)

@muhammadaliimranbjalaludin653 10 ай бұрын

Basically we consider the outcomes as ordered quadruples. For example, if there are 4 people, (1,2,3,4) can denote the outcome that everyone receives their hat. (2,1,3,4) denotes the outcome where the first person takes the 2nd guy's hat and the 2nd guy takes the first guy's head and the rest got their own head. So, you can consider the total number of ordering in this ordered quadruple to be 4!. Also, derangement here considers all cases where the i-th entry is NOT EQUAL to i, for all i.

I loved your videos, especially the underfitting and overfitting one. For this one I would just say it got a bit typical towards the end to understand the concept of why exactly alpha > p- value leads to reject null hypothesis. But still great work though!!
