+Brandon Foltz , hi there nice videos ! do you have any video on how to account for confounding and effect modification in multiple regression analysis?
Brandon Foltz can you please explain how do I interpret different standard errors for different regression coefficients in the multiple regression model. I understand that in simple linear model it's the average distance data falls from the regression line but there we have only one regressor variable whereas in this case exists more than on regressors so can you please explain that?
@tomaskovarik1215 teacher myself and I can attest that Brandon's lectures and explanations are clear, professional, easy to understand and yet rigorous.
Thank you Brandon!! Your words of encouragement were just what I needed to hear and your straightforward way of presenting the material is such a relief! Thanks for doing what you do!!
Hey Brandon, taking my second stats course this semester along with pre-calculus 2. Your videos are invaluable. I start this Tuesday and am using your videos to get an overview of what I am going to be learning. Thank you!
Thank you Martin ☺️ Many lecturers nowadays are stretched very thin have have good intentions. I am glad your time learning with me was helpful and I have no doubt you will continue to do great things. Onward and upward!
I love the level of care and detail which you approach your videos with. Many other channels seem to cut corners in that regard and as a result, the videos are not as effective for me. I greatly appreciate your effort!
For some reason I don't like posting comments, but I have to let you know much you have helped me, you are one of the best teachers, or the best teacher I know. Thanks a lot
I heard your opening motivation in another of your videos and have written it down to read to myself when I inevitably find myself panicking over a problem (math or otherwise) that I am struggling to overcome. Thank you for that.
Really nice and helpful video lectures. Brandon it would be great if you can make videos on 1. Logistic regression (for binary output) 2. Multivariate Logistic Regression (for continuous output). Thank you.
Thanks so much for these videos! I am finding them very helpful with my studies on linear regression. You break it down in such an easy way that I seem to comprehend. Also, I love the words of encouragement at the beginning of these videos!
I just found this wonderful resource after freaking out about probably not passing my honours course. THANKYOU! the opening made me feel so much better :) xx
Thank you sir for taking the time for leaving this lecture on youtube, I know it takes time amidst this busy life, I appreciate it very much, it helps me a lot, very clear, right pace, and meaningfully keeping all important points.
Hey @Brandon Foltz ! Two doubts: 1.) Remember in your previous videos when you laid out the formula for prediction interval and confidence interval. In case of prediction interval the formula for the interval was (y*)^ +t subscript(alpha/2) * (s(subscript (pred) )^2, where (s(subscript (pred) )^2 = s^2 + (s (subscript y*))^2 s - standard error/RMSE s (subscript y*) - term which appears in confidence interval formula. difficult for me to expand it here, you mentioned it in CI video. But in this video when you were calculating PI for x=84, you multiplied directly by standard error(RMSE) of 0.3423. Isn't it wrong? 2.) If R square = SSR/SST *100 , and SSR = SST - SSE, and Standard Error(s) = SSE/SST * 100, why in the table which is shown in the end, they don't add up to 100% for all the three variables. R sq %+ S% = 100%, right?
Thank you so much for your video Brandon, I listen since the Simple Linear Regression, and all of your video have helped me a lot. I used to repeating what my teacher teach for hours and still did not get it, but once I saw you video, I immediately understand. Thanks again and God Bless.
The videos are very informative. I bet these videos contain something that no one can ever easily find inside a book. I must say "read books and do watch Brandon's videos," you'll be a master in regression analysis.
Amazing video! I enjoy learning stats even more! No one had ever run through all the values of the results with me before. I really appreciate your effort and patience.
Thank you for the pep talk in the beginning. Mathy stuff isn't my forte but I need stats for my social science research, so I push through. Thanks for not being one of those teachers that make students feel bad
I am studying machine learning so i wanted to become strong in statistics . Your videos are very helpful. i can see your effort and hard work . Thanks a lot :)
Thank you soo much for these lessons! I'm using them for econometrics, I don't uderstand anything at lectures and now it all finally makes sense! Also, the revision parts from previous videos are very helpful :)
this is my first stats course and because my teacher is only using SPSS I found it difficult to follow. I realize you could not do every software just wished you used SPSS but everything else you have done in stats has been helping me more than you will ever know thank you soo much
Awesome video, wonderfully explained. Can you couple these videos along with a 3 min session (at the last point of video) in SPSS so that it becomes easy for the user to see how to implement the concept.
At 16:44 if you want a 95% confidence interval shouldn't you use the 0.025 value since the interval is two-tailed? If you use the 0.05 value won't that result in a 90% confidence interval? Just curious if I am correct in my thinking or not! Thanks! Great videos, fyi :)
16:03 sir, here we are using 's' as an approximation of s-pred, right? S-pred= 0.3599 which is almost same as 0.3423. Please let me know if I am correct.
Very stressed grad student currently crying after the intro... very well done!
I never posted a comment online before, but I had to in this case. Brandon, you are absolutely awesome individual and a very effective teacher.

The beginning pep talk was greatly appreciated
The beginning of this video was so needed. Thanks, Brandon!
I am a math teacher myself and I can attest that Brandon's lectures and explanations are clear, professional, easy to understand and yet rigorous.
My next Multiple Regression video is now live! Just FYI that it is a two part video. Enjoy!
+Brandon Foltz , hi there nice videos ! do you have any video on how to account for confounding and effect modification in multiple regression
analysis?

This world needs more teachers like you. A big thankyou for making it so easy to understand!

These playlist are amazing and very useful. I am watching alongside as I analyse my data.
Thank you brandon. I am glad I came across this video.
Thank you Brandon!! Your words of encouragement were just what I needed to hear and your straightforward way of presenting the material is such a relief! Thanks for doing what you do!!
Why am I only learning about your videos today 😭. They are really good and helpful. ❤️. Thank you. From South Africa 🇿🇦
Hey Brandon, taking my second stats course this semester along with pre-calculus 2. Your videos are invaluable. I start this Tuesday and am using your videos to get an overview of what I am going to be learning. Thank you!
Brandon you put my statistics lecturer to shame when it comes to explaining these concepts in a way that makes sense!!
Thank you Martin ☺️ Many lecturers nowadays are stretched very thin have have good intentions. I am glad your time learning with me was helpful and I have no doubt you will continue to do great things. Onward and upward!
Brandon you are amazing. THANK YOU SO MUCH. You don't know how much you have saved my life.
I love the level of care and detail which you approach your videos with. Many other channels seem to cut corners in that regard and as a result, the videos are not as effective for me. I greatly appreciate your effort!

Thanks, Brandon for the encouragement. You are a super awesome teacher. God bless you.
My professor is pretty good, but your slides and tempo are just better for someone who's slower in learning statistics! Thanks so much!
Thank you for the sweet pep talk and your hard work!!
I heard your opening motivation in another of your videos and have written it down to read to myself when I inevitably find myself panicking over a problem (math or otherwise) that I am struggling to overcome. Thank you for that.
What a lovely preamble. Funny - such a small thing, but I appreciate it so much. These are great!
Really nice and helpful video lectures. Brandon it would be great if you can make videos on 1. Logistic regression (for binary output) 2. Multivariate Logistic Regression (for continuous output).
Thank you.
Brandon, aren't you just absolutely awesome?.No doubts...your heart is pure gold!!.
Thanks so much for these videos! I am finding them very helpful with my studies on linear regression. You break it down in such an easy way that I seem to comprehend. Also, I love the words of encouragement at the beginning of these videos!
you have a teaching gift that was so simply expained
I just found this wonderful resource after freaking out about probably not passing my honours course.
THANKYOU! the opening made me feel so much better :) xx
Trying to consistently thumbs up every single video in all the 18 playlists

I have the same question as your first one!

You are awesome sir!!!
***** Awe thanks! But you are awesome-er. :)
Thank you very much. The introductory sentences, specially the Benjamin Franklin's quote, were very encouraging :)
the little affirmation at the start gets me every time :') i needed that :')
Thank you so much for your stats videos. They make total sense when compared to some of the rubbish my uni lecturer attempts to present.
Great lecture truly breaks down the concept of multiple regressions. Thanks
Thank you so much for the intro 😭 I need to have faith in myself and to my groupmates. We can do this!!!!
Amazing video! I enjoy learning stats even more! No one had ever run through all the values of the results with me before. I really appreciate your effort and patience.
watched your videos on basic stats almost from the the beginning. it really helped a lot. thanks.
Iam grateful that you sharin your knowledge in easy to understand way to all of us

Amazing teacher!
Thanks a lot for the video,kindly make some video on logistic regression please.
Sayantan Sen Thanks! I am working on Logistic Regression right now actually. :)
Great sir. We are eagerly waiting for those videos .
this is great!! thank you!! the motivational speech was much needed lol
Thanks Brandon...These videos are very useful.
Brilliance personified !
Excellent videos....highly recommended ! Thank you
the best statistic video is of jbstatistics.Beside that genius if anyone that explains beautifully then its you.
At 16:44 if you want a 95% confidence interval shouldn't you use the 0.025 value since the interval is two-tailed? If you use the 0.05 value won't that result in a 90% confidence interval? Just curious if I am correct in my thinking or not! Thanks! Great videos, fyi :)
Excellent explanation and comprehensible although I'm not a native speaker. Thank you!
Thank you so much for making these videos
This is SO clear. Thanks!!!
Thank you for these videos!
that intro really got me fired up haha. nice video
Um, that little pick me up at the beginning? Thank you!
I like the pause he makes makes at 21:26 while saying "that's... very low", almost as if he's disappointed by how low it is
Welcome to my life...😂
excellent ... thanks a lot... It helps me a LOT...
16:03 sir, here we are using 's' as an approximation of s-pred, right?
S-pred= 0.3599 which is almost same as 0.3423. Please let me know if I am correct.
The video is really great!! It helps me a lot ! Thank you !
