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 :)
looking at the comments, everyone is so satisfied with his explanation. how i wish the name of this channel was statisfaction.
lol
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
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?
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.
Wow! Thank you so much for such a wonderful compliment. I was going to call my company, "MyProfessorSucks" but went with "MyBookSucks" instead. Make sure you like MyBookSucks on FaceBook (see link in video description). This will help others find the educational videos.
I went 360 degrees to learn this concept, and finally, you made my day bright. STAY BLESSED!!!
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!
8 years later, you saved my life! THANK YOOOOOU!!!
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!
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 :)
Love the style of teaching, breaking down every possible step with ultimate visual representation
I was sick of the SST, SSR definitions and wanted to refresh what I had learnt in school. This was super helpful!
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 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.
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!
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.
Top notch use of technology (animations) to drive the concepts home. Simply marvelous !!
I was looking for such simple yet effective explanation, Thanks Prof !
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.
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
this guy is not only brilliant but transformative, God bless you abundantly my brother wow
I Think you are the best guy of statistics i ever seen.................................in a word you are a great!!!
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
This video explained in 7:40 minutes what my Professor couldn't explain in 2 Hours of Lecture Thank u so much Thumbs up !!!
12 years later, you saved my life
Great to hear! Not that your confused but my videos are helping you. I have always thought that animations help students learn.
Great to hear and thanks for helping me spread the word.
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.
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
Love your videos! They are so clear and easy to understand. Many thanks!!
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 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.
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
wow thank you so much, you just saved my exam! keep the good work up, people really appreciate this!
Thank you so much for sharing your knowledge. Your videos are by far the best I have watched on linear regression.
Great video and excellent explanation- who knew statistics could be so calming!
Nine years ago and still very useful. Thanks for sharing.
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.
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 🥰🥰
Excellent!! thank you :), I really liked the visuals and they're so much easier to follow than other videos!!
LR algorithms explained well. Thank you for your time and effort.
Glorious, wish I had a lecturer like 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.
Great to hear the videos are useful!
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 :)
Very well explained. GOD BLESS U. Thanks for your dedication to the community.
I really like your meticulous demonstration. Salute you for such volunteering.
Your Graphics are ultimate!
Very simple yet so informative. Thank you sir!
Best video ever for statistics!
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
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!!!!!!!!
quality videos for 2012 creations. Respect.
Amazing video. You have simplified the concept so much. Thanks a lot
the way you explain.. AMAZING ....Do you have factor analysis and cluster analysis videos?
If yes then pls share the link.
Fantastic and superb concept! wonderful tutor
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).
Party more study less is a BIG MOOD
You are fantastic. I look forward to watching you more
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.
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.
Thank you for such kind words it is much appreciated.
Thank you so much for that explanation! You made it so simple!
bless your soul, sir. I think you saved my exam mark...
The video series are greattttt!!!!!!!! You made it so easy to understand. Thank you so much!
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 good, i like your video, simple and enough to understand the complex statistic algorithm
You are a good teacher, keep it up.
Thanks for such a clear and concise explanation...really feeling exciting about learning statistics more..keep it up.
Very simple and clean. Thank you
I really Like the way that you explain the Topic easy and understandable thank you
Thank you! your way of explaining statistics is cristal clear!
Great sir.indeed very helpful
Love and respect from Ghulamdaag, Nangarhar, Afghanistan
Excellent explanations!
Thank you so much for posting these, incredibly helpful!
Thank you for explaining it with real numbers.
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!!!!!!!
Thanks to this video I could do the calculations for my thesis!
unbelievable work. very professional. 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
Ok, Thanks very much for replying. I was able to find a way to do it manually. The equation for a non linear coefficient of determination is
1-(SSE/Syy).
Great tutorials by the way, they are a real life saver!
What a wonderful compliment! Happy to be your statistics god! Hopefully my videos will help you pass your final -- good luck.
Make sure you like MyBookSucks on Facebook (see link in video description). This will help other students find the videos, so they don't "freak" out on their finals!
Thank you so much for uploading this video it is simple and cut throat to the point loved the whole series of regression analaysis 😀
Simple and precise explanation .Thank you
Really felt like learned something finally. Thanks for the video.
Great work sir❤🙏
Excellent !!!!!!! Superb !!!! - Video and Explanation both are great - No doubt left
Thanks a lot
Very very clear explanation. It was a bit confusion for me since you do this without determining the regression line y=mx+b. But I've tested both way (with figure out y=mx+b first then calculate Rsquared=1-(SSE/SST) compared to yours) and give me same results. Great, your method is simpler and save some time...!!
Agung Enriko Thanks for you comment. I try to do this a simple as possible and design in such a way that it can easily be put into a spreadsheet. Happy to hear that you are finding my method a bit easier.
great videos, great content, brilliant way of explaining things. Thank you
such an awesome video guys don't miss to watch this video it will help u to understand easily what is regression thank you sir
I love you sooo much....thanks alot ....there is no better explanation to understand this
wooow .. i have seen like hunderds of videos to understand this damn R squard .. I just niw got .. u r brilliant .. really .. thx alot
you made statistics easy. Thank you sir!
You made the things very easy.Thanks
appreciate your hard work in taking time to create this video which is really worth million thanks.. such a great explanation about linear regression ...kudos to you .. i am looking forward for classification,clustering and recommendations from you as i am preparing for Data science certification
