looking at the comments, everyone is so satisfied with his explanation. how i wish the name of this channel was statisfaction.
lol
At some point i had lost hope about learning anything of Statistics...But there are some great people like you who are helping the one in need. Allah bless you with better health and long life.
what you said is correct.
Hamidullah Khan me too brother , keep learning
@josetogan Stop being a loser is my tip to you :) People are here to learn. Let them learn.
@josetogan Who told you there is a conflict between science and God ? many scientist believe in God ! Stop believing in superstitions and rule your mind is my tip.
@moataz Siraj, more than this guy's questioning God, I'm questioning his sanity and maturity. Must be having the time of his life to be able to come out of a hole for this discussion as the reason of his sad and pathetic existence is to try and push his believes on people (on random videos). On the plus side, the video is spot on and hopefully he has learnt a thing or two here. Regarding his theory, he will live to figure out what he calls "superstitions" when the time comes. I've seen many turn around :)
I bought a linear regression book and I cannot tell you how much better this is for someone with a non-stat background. Thanks dude, for real.
Thanks for the feedback much appreciated. Maybe you should send your professor a link to this video and the playlist on regression :). Make sure you tell your fellow students and like us on facebook (see link in the description of the video).
Good luck in your class and let me know if you need/want other videos. I am always looking for ideas.
David
Sir, you are amazing.
Can we take the difference between y-hat and y and use the squared average to evaluate the goodness of fit?
This is mind blowing....two years of lectures not understanding this, and i watch a few videos on here, and I'm finally getting it
These seriously summed up at least a month of classes on correlation and regression for me. Thank you SO much. Please please PLEASE do more of these!
I went 360 degrees to learn this concept, and finally, you made my day bright. STAY BLESSED!!!
8 years later, you saved my life! THANK YOOOOOU!!!
Respected sir, I have started my course in Big Data and Business Analytics and have these concepts of least square and R squared. The way in which you explain the concepts along with the awesome animations... I consider myself very lucky to have stumbled upon your channel!! You are simply FANTASTIC!!! Probably the best videos on such important topics where they seem so simple... Thank you so much for such wonderful explanations sir :)
Neo this video is part of a larger playlist on regression. The link to the entire playlist is in the video description. The first video I show you how to derive the equation.
Happy to hear that the video helped you. It is important to know where and why such as R2 (squared)
Make sure you like MyBookSucks on FaceBook (see link in video description). This will help others find the educational videos.
There are simply not enough superlatives to describe this series of videos, your understanding of how to explain statistics to young adults is without rival. Thank you for taking the time to make them.
I'm always so clueless in my statistics class. But wow this is great! Thanks Mr. Longstreet!
Thank you for you compliments.
The standard error of the estimate is different than R squared. In the video description you will find a link to a playlist on Regression. I have a video that explains standard error of the estimate too.
This video is part of a playlist "Linear Regression" on my channel statistics fun. I explain how to calculate 2.2 (the y intercept). The name of the video is "How to calculate linear regression using least square method.
I added a link to the playlist in the video description, so you should be able to find the video.
Let me know if this does not help.
Many thanks and it is my plan to keep posting and improving the videos/animations. If you have not done so make sure you like MyBookSucks on FaceBook (you can see the link in the video description). This will help other find the videos too.

Ankit, You can find an entire playlist on regression in the video description of this video. In the first and second videos I explain how a regression line is built.
I was sick of the SST, SSR definitions and wanted to refresh what I had learnt in school. This was super helpful!
You are very welcome! Make sure you like MyBookSucks on FaceBook (see link in video description). This will help others find the educational videos.
the fact that u add party more study less at the end of every video makes me feel less guilty and less stressed. thank you so much!
Thanks for the video series. I'd done regression in college, in the early 90s and really hadn't done them ever since. Your videos brought it all back
I plan to keep posting more and more... just getting started.
Kirby, thank you! I appreciate the feedback. Make sure you like MyBookSucks on FaceBook (see link in video description). This will help others find the educational videos.
I gotta say I love what are you doing. All these videos out there got my head messed up. I finally got it. Thank you thank you thank you! More people like you are certainly needed.
Thanks for the feedback. It means a lot to me. The South Pacific always sounds like a beautiful place to me. Make sure you take a study break/fun/humor and visit MyBookSucks on Facebook (you can see the link in the video description).
Thanks again, good luck in your classes and enjoy the beauty of the South Pacific (great movie too).
Someone once said that if you couldn’t reduce it to the freshman level. That means you don’t understand it. Mr. Statistician, you possessed a rare ability to understand and explain it so that even a six-year-old can understand it. Thank you for helping me learn statistics!
Thank you so much for your step-by-step, clear, understandable videos. I really appreciate your calm voice and your sense of humour, too.
I was looking for such simple yet effective explanation, Thanks Prof !
12 years later, you saved my life
Top notch use of technology (animations) to drive the concepts home. Simply marvelous !!
Hi, I was confused in my Lectures here at university of Sydney and in about 3 videos I've watched so far, I understood regression. You are very clear and videos are super simple
Sir, i don't feel like moving away from my system. I bow you for your excellent teaching capacity ... God bless u .. I wish I can met you at least once, in my life time
I wish I had found this resource at the beginning of my course. This video is more understandable than my online text books. Thank you for doing this.
I Think you are the best guy of statistics i ever seen.................................in a word you are a great!!!
the way you explain.. AMAZING ....Do you have factor analysis and cluster analysis videos?
If yes then pls share the link.
Great to hear and thanks for helping me spread the word.
Simply EXCELLENT! Very Clear. Thank You!
You are awesome!!!!!!! You have taught me more in 4 videos than what my prof has tried to teach me in 6 classes. My prof is so dry and has no clue of how to teach. He just rants and mumbles AND is all over the place that it's hard to follow him. Thank you so much for putting up your videos and helping me out!! At least now I stand a chance of passing this course.
Great to hear! Not that your confused but my videos are helping you. I have always thought that animations help students learn.
Thank you for the Video mister!There are people still watching these videos so i would like to ask for some R analysis on Linear Regression.
Keep up the good work!
Very nice video series - very clear, not too fast, and not too complex. Your method of presentation helps to connect a lucid conception of what one is trying to accomplish with the step-by-step procedure for doing it.
Well, thank you very much for the compliment. btw, love the avatar.

this guy is not only brilliant but transformative, God bless you abundantly my brother wow
advantage that we(student) gain watching your vids is clear explanation aided by your clear voice + graphical representation of concepts... hats off sir..its a pleasure to learn more
@cool4skull I use a variety of different tools including illustrator, flash, photoshop and then stick all together.. So there is not one single tool I use.
This video explained in 7:40 minutes what my Professor couldn't explain in 2 Hours of Lecture Thank u so much Thumbs up !!!

Hamidkhan said the best words to express this....
everyone can teach,.......but only a few like you u can teach things so simply.
Thank you very much
God bless you
This is just genius explanation of how to find r squared because I had so much trouble to understanding the whole idea of regressions nor just finding r squared
I don't have any on those topics yet, but it is a good idea. Make sure you like MyBookSucks on FaceBook (see link in video description). This will help others find the educational videos.
Great to hear the videos are useful!
I have watched many videos of Statistics but you are the best. I like the graphics which helps me to understand statistics a lot better than what my teacher in school tried to teach. Keep making such tutorial.
Love your videos! They are so clear and easy to understand. Many thanks!!
i watched all your videos regarding correlation and regression. i love how u explain everything . its so clear . usually im a slow learner but i can understand everything u explained in the videos. couldnt thanks more 🥰🥰
I was always amazed by statistics and probability, but when I took the course at the University the book had many errors and the instructor wasn't eager to teach. I'm thinking to do myself a favor get this out of my system. Good video.
Thank you so much for sharing your knowledge. Your videos are by far the best I have watched on linear regression.
Excellent!! thank you :), I really liked the visuals and they're so much easier to follow than other videos!!
Thank you for such kind words it is much appreciated.
Great video and excellent explanation- who knew statistics could be so calming!
Nine years ago and still very useful. Thanks for sharing.
wow thank you so much, you just saved my exam! keep the good work up, people really appreciate this!
Glorious, wish I had a lecturer like you ...
I'm learning statistics after so long and i always disliked it in school because I never understood it but now I'm learning data science so I need to know and I have to let you know because of you I started liking it as finally after so many years I found someone who can simplify it. Thank you
Very simple yet so informative. Thank you sir!
I really like your meticulous demonstration. Salute you for such volunteering.
Thank you for your video. I learned so much of the topic in few minutes, which I could not learn in last three of my classes.
Very well explained. GOD BLESS U. Thanks for your dedication to the community.
Party more study less is a BIG MOOD
the best regression analysis and R Squared tutorials I have seen
You defiantly give Khan Academy a run for his money with this. Keep up the good works and thanks :)
I like the way you analyze. Go on Brother and disclose all the knowledge which you have within you. Wishing God to give you a solid stamina to make the videos of all the contents of the memory card of your mind. Last, but not the least, a lucid analysis of statistics has been helping me for the best interpretation of different research results (From Nepal, with love and respect).
Amazing video. You have simplified the concept so much. Thanks a lot
Your Graphics are ultimate!
This is such a useful video. I knew that the closer R^2 is to 1, the more accurate the forecast is, (Told by the instructor), but it was never explained clearly like the video.. Thank you!!!!!!!!
clear and simple explanation, you made it confidence
Aravin Prince Periyasamy Make sure you share the love, If you get a chance make sure you like and share the videos, it will make it easy for others to find them.
Sure professor
is it the same equation as R2=SSR/SST ?
_clear and simple explanation, you made it confidence_
You made it confidence? What does that even mean? Slumdogs always struggle with English.
LR algorithms explained well. Thank you for your time and effort.
Thank you so much for that explanation! You made it so simple!
bless your soul, sir. I think you saved my exam mark...
Thank you for explaining it with real numbers.
Fantastic and superb concept! wonderful tutor
WOW!! Very nice video. I had gone thru many videos or better explanation for regresion analysis. But, atlast I found this video, with better calrity and the explanation and presentation is superb, which even a layman can understand. Thank you very much.
Tom - good question on regression. There is a link to 2 playlist in this video description. The first is on regression the 3rd and 4th videos should help. The 2nd playlist on how to read the SPSS regression output. I go through step by step what the data means.
If this does not help, then post your question as a message on MyBookSucks FB page (you can add an attachment with your problem). Again the link is in this video description.
Good Luck!
Thanks for such a clear and concise explanation...really feeling exciting about learning statistics more..keep it up.
Thanks to this video I could do the calculations for my thesis!
Thank you so much for posting these, incredibly helpful!
Thank you! your way of explaining statistics is cristal clear!
The video series are greattttt!!!!!!!! You made it so easy to understand. Thank you so much!
You are fantastic. I look forward to watching you more
you are great!! Thanks for helping me quickly review this thing I have learned a million times but forget till the next time I need it (every five years). Looked through a bunch of youtubes - this was the best. THANKYOU!!!!!!!
Best video ever for statistics!
Seriously thanks a lot for your time to prepare such wonderful animations and teaching. I am neither math not statics student. IFRS 9 needs to measure Expected credit losses(ECL), as you understand - expected involves probability and regression. Thought of having an idea of basics. your lectures helped me a lot. Thanks a lot and God bless you with superb health.
Simple and precise explanation .Thank you
Really felt like learned something finally. Thanks for the video.
Very simple and clean. Thank you
sir you are really doing great. Please make these type of videos in future. Really these videos are helpful in clearing my doubts and I prefer to watch your videos than reading books
