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.)
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!
I agree with the graph, very helpful to see the distribution graphically!
I also agree. That was a perfect video
@@jbstatistics this cleared up so many things for me, i am forever grateful ToT
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!
Thanks for the kind words! I very much hope you find my videos helpful. Cheers.
You Sir, are a legend.
Thanks!
Sigma JB😅
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
Thanks!
1:00 "And if we're interested in the number of trials to get the... TWELFFTH success.."
Lmao hidden gem
natedsamuelson LOL what was that lmaooo
I nearly spit my coffee out when that happened hahahaha
LMAO
You've done what my professor and book couldn't. That is to make me understand this in 7mins!! xD
+BOB BOB You're welcome!
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.
I cannot thank you enough for your videos. They are so helpful and are getting me through my stats class. Very clear and concise!
This discrete probability is one of the least talked-about functions. You spell it out great! Thank you.
I have never understood this concept until watching your video. Super clear and helpful!
I'm glad to be of help!
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..
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.
The difference a good instructor makes. So glad I go to college while having access to RUclips. I feel bad for everyone who didn't.
I'm glad to be of help!
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
Watching the video after 10 years of upload and still getting benefit from this. Thanks for the clear explanation.
It's still good stuff :) Glad to be of help!
man, i had to drop prob and stat class because i couldn't grasp the concept and here we are, crystal clear. Thank you
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 !
i love how u mix with humor to keep us focused
Very well explained, all my confusion is gone. Thank you very much!
Your videos are at the rescue when strucked middle of any maths topic. 🙏 Hats off to your hard work.
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.
You're welcome! I try hard to be concise in my videos, while still getting the important points across. (So I like to hear that word!)
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 :)
After 2 days of trying to figure out all the differences I finally understand. Thank you soooooooo much
It has been useful for me after 8 years. Thank you sir.
You are very welcome! I built them to last the test of time :)
You are welcome, and I'm glad to be of help. I hope your semester went well.
if i saw your video few months ago my grade would have been a lot better. Thank you so much.
Seriously, I have understood the concept of distribution after watching this video.And those graph is so helpful. Thank you so much sir....
I'm glad I could help you understand!
Great stand-alone video to learn about the negative binomial distribution.
thanks a lot man, you saved me..you can't understand how useful your lessons are....keep goin!!!!
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.
Thanks for the compliment! I'm glad I helped you see it. Cheers.
The way you teach is frekkin AWESOME!!!
Thanks!
If Khan academy is the Walmart of learning videos, then you are the store that delivers the groceries straight to me! lol
Well, I do aspire to be better than the "Walmart of learning videos"!
Khan academy does not cover quantity... it is slow.... this is fast .... good .... straight to the point
My semester is great thanks to u pls do keep up we need more selfless people like u
my prof skipped this in probability theory, thank you so much u explained it so well
Your lecture is clearer than what my professor put on board. Thank you .
An excellent explanation of this distribution. Very clear and easy to follow.
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!
Well explained. organized presentation, no waste of time. A natural teacher. Must be a well-organized person in life. Thank you.
Yes sir, I found ur video very useful for my students in University of Indonesia, Jakarta
exceptional teaching style
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.
this is the video. the one ive been looking for
Thank you very much, your videos are excellent! I learn the concepts much easier by you than by my professor!
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.
I give the mean and variance at 4:19, just after discussing the pmf.
This explanation is sooo clear and precise thank you sir you are amazing
You are very welcome. And thanks for the compliment!
This is such a helpful video for building intuition about these distributions.
Best impact I’ve ever experienced
I coded the diffrence between binomial and negative binomial in my mind as, like the diffrence between period and frequency. Thanks for the videos!
I might answer questions to clarify a point on a video, but I don't answer other questions or help with homework or assignments. Cheers.
You make this looks like Kindergarten Math, much appreciated.
Wow, you make it look simple! You have a gift! Awesome.
Excellent and clear step-by-step explanation. jbstatistics, Sir, you are amazing.
Thanks for the compliment!
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.
This is really well explained.
May God give you immensely!❤
You explain so well.
wow maths is beautiful when you really understood good
Your explaination is so clear! Thankyou sir! It helps me a lot!
You are very welcom!
thanks a bunch!!!you've made all the distributions really simple
You're welcome! Glad to be of help!
Please do videos on jointly distributed random variables. your videos are the only reason I am passing my prob class so far
Thank you sir.with the help of your teaching,l easily study the formula's sir
Thanks for the explanation sir
Great explanation, you’re a legend
This video helps clarify a lot of confusions!!
I'm glad to be of help!
@ 6:19 How would you multiply the (10-1|3-1)*0.09^3?
the numbers in the parentheses is a combinatoric notation
@@DaffaAlifPratama THANK YOU SO MUCH
good good stuff, i have a quiz today so you just saved me.
honestly, this helps so much. SO MUCH. Thank you SO MUCH
Thnks justin beiber statistics..i am gonna devour your all lectures.
Because we're interested in the probability that the rth success occurs on exactly the xth trial. For this to happen, 1) the first x-1 trials must contain exactly r-1 successes and 2) the xth trial must be a success.
To find the probability that in the first x trials there are r successes, where x is fixed, we'd use the binomial distribution.
The probability that the rth success occurs on precisely the xth trial is less than the probability of getting r successes in x trials.
Very concise and informative! thanks!
thank you so much man, u have been helpful through out my semester
so good man. so understandable! keep the work up! wish u success in your academic life!
I'm glad I could help, and thanks for the kind words! All the best.
Very helpful!...
Please keep uploading videos.. your videos are very helpful. Thanks...
Your videos are extremely helpful! Thank you so much!
You are welcome!
i can't thank you enough god bless you❤
Great Explanation.
Thank you for this great video
Great tutorial on Negative Binomial Distribution! Could you please also explain what is overdispersion parameter in Negative Binomial Distribution?
I was scratching my head for hours on this distribution, then i found your channel xD
Great explanation. The video was clear in informative!
Do you ever become angry that professors are getting paid crazy amounts of money but doing their job so poorly that people have to come to learn for free from you? I would. Thanks for the great explanations.
Not really. I'm a professor so I'm okay with it :) I do these videos primarily for the benefit of my own students, but I'm happy to make them available for the rest of the world. Cheers.
great explanation.. Would have been exemplary if the derivation of mean and variance would also have been shown.. But it's stellar nevertheless.. helped me understand the difference between binomial and negative binomial.
Great lecture video! Thank you so much!
it's the voice for me, sounds like SwaggerSouls is teaching me maths
thanks a lot, very well explained
you saved my life. thank you
wonderful video, months trying to comprehend formulas with no explanation and this solved my problems in 7 minutes and 32 seconds, create a website so you can get payment for this shit, its amazing.
Thanks for the very nice compliment! I'm glad to be of help!
Sir, thanks for the help. Please make conceptual video on sampling
Thank you so much for this video! Explained a lot.
You are very welcome Allan!
Thanks! I'm glad to be of help.
AHAA! now i get the relationship between Geometric and Neg Bin Dist...thanksss
You are welcome!
Great explanation!!! Pls upload a video on beta and gamma distributions....
Thanks a lot, wicked teacher!
You are very welcome. Thanks for the compliment!
Thanks a lot, that was incredibly concise!
