Introduction to the Negative Binomial Distribution

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

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!!

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.

These videos will go down in history as one of THE best
GOATED stuff right there fr fr no cap ong. the explanation do be bussin respectfully

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.

[shreya]

the best video for this topic !!!! the formula in my book was very complex and here I found the simplest method to solve the question. thanks a lot

[bamakaze]

This discrete probability is one of the least talked-about functions. You spell it out great! Thank you.

[SonDVo]

I have never understood this concept until watching your video. Super clear and helpful!

[venkydk]

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..

[gabrielfitzpatrick]

I cannot thank you enough for your videos. They are so helpful and are getting me through my stats class. Very clear and concise!

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

[bobjohnson]

You've done what my professor and book couldn't. That is to make me understand this in 7mins!! xD

[eraludeck]

Your videos are at the rescue when strucked middle of any maths topic. 🙏 Hats off to your hard work.

1:00 "And if we're interested in the number of trials to get the... TWELFFTH success.."
Lmao hidden gem

[muhammadazeemmohsin]

Watching the video after 10 years of upload and still getting benefit from this. Thanks for the clear explanation.

[TrendRain]

man, i had to drop prob and stat class because i couldn't grasp the concept and here we are, crystal clear. Thank you

[andrewagita]

i love how u mix with humor to keep us focused

[jbstatistics]

You are welcome, and I'm glad to be of help. I hope your semester went well.

[jbstatistics]

You're welcome, and thanks! Different strokes for different folks -- I'm sure some of my students leave the same comment on other youtube channels :)
