An introduction to the negative binomial distribution, a common discrete probability distribution. In this video I define the negative binomial distribution to be the distribution of the number of trials needed to obtain r successes in repeated independent Bernoulli trials. Different sources define it in different ways (the distribution of the number of failures before obtaining r successes, for example.)

Thanks for the kind words! I very much hope you find my videos helpful. Cheers.

Its actually unfair the amount of value you give in these videos. It took me 10 minutes (7 minutes + replaying some parts) to understand a topic, something my professor could never do. And even if I relied on the good old textbook, I still wouldn't understand it this quickly. God bless

I'm glad to be of help!

@ghadaabu-sheasha4278 8 лет назад

You are amzing! There are two brilliant parts. The first one is 1:15 when you differentiate between binomial and negative binomial distributions. The second one when you show the distribution in a graph at the end of the video. VERY WELL DONE!!

+Ghada Elsayed Thanks!

@usaTutor1 7 лет назад

I agree with the graph, very helpful to see the distribution graphically!

This is great..I went through several Edx ,they were so mathematical that we get lost.Your explanation helps to fundamentally build whats exactly needed for this topic..

Thanks Mohammed. I'm always glad to hear when people find my work useful. I'll definitely be keeping it up and adding videos. All the best.

@JimbobFaz 5 лет назад

Great video, my book explains this way to fast and this really helped. I can see myself re watching these vids a lot before my module is over.

@narimanpashayev6309 3 года назад

Your videos are really helpful and explain every detail precisely. I recently started learning statistics. it was very hard for me to understand and the digest the statistics concepts. But then I found your channel and I am very thankful to you :). I really appreciate your efforts here.

@aarushialreja2089 Месяц назад

I could not understand this from my stats textbook even after trying for 30 whole mins(even the formula didnt make much sense to me without proper explanation) and it only took me 7 mins to understand it so well here.. thanks for this honestly.

@anandraj6345 2 года назад

I am watching this in 2022 and this video is still the most accurate and the best video on Negative binomial distribution or any topic u pick of statistics and probability. THANKS A LOT PROFESSOR! #luv_from_INDIA

@48jackpotjohnny 11 лет назад

Excellent video! Explained very clearly and concisely. Thank you for taking the time to do this. I'm looking forward to watching many of your other videos, as I'm assuming it will make my future studying much easier. kudos to you for a job well done!

@diyasharma96 4 года назад

Superb stuff. Clean visuals, intuitive explanation, and helpful prods about potential misunderstandings. Some Ivy League professors struggle for hours to teach these concepts in a useful, unpretentious way, and then you come along and make it so easy that it can be digested in 5 minutes. For embarrassing some overpaid hacks of Harvard, you deserve a proposal of marriage or something.

Oh my! I love your videos, but I was hoping to find out mean and variance of this distribution and there isn't. Thank you so much for your amazing explanation. Cheers.

@jbstatistics 4 года назад

I give the mean and variance at 4:19, just after discussing the pmf.

@TimothyChenAllen 11 лет назад

Great explanation; I'm working through Hogg, McKean & Craig and could not understand how they arrived at the negative binomial pmf; seeing how you did it made it clear. Oddly enough, your explanation made clear to me how the text was explaining it the same way; I just couldn't see it.

@HimalShrestha 6 лет назад

Great tutorial on Negative Binomial Distribution! Could you please also explain what is overdispersion parameter in Negative Binomial Distribution?

@srinivasanp.b9914 8 лет назад

You could even look at this way. For example, in the sum on telephone calls, you could simply model the problem as a binomial with X=2 and then multiply P(X=2) by 0.09 to get the answer !! Doing this might help you get an intuitive sense of the negative binomial distribution and what it hopes to achieve. Think about it !
