Correction:
2:49 I left off some of the parentheses for the equation for F. The numerator should be: (SS(mean) - SS(fit))/(pfit - pmean)

Let me tell you this: I was crying in fetal position 4 hours ago; until I saw this video. So THANK YOU for your brilliant channel! 🙏🏻👐🏻

[速战速决-vq]

I almost gave up on statistics until I saw your videos. Now I can confidently say I understand most concepts here.

Comparing the simple & multiple regression efficiency through the difference of R². As simple as that. Love it. Thanks for making stats fun

First, you are an awesome, caring and friendly teacher and your way of teaching is very effective! Love your songs too! Second, would you consider covering historical uses of multiple linear regression, statistics and linear algebra? For instance, I read in my linear algebra textbook about how a russian mathematician used linear algebra to try to help the soviets logistical war effort during WW2 and also how an American economist used linear algebra during the late 1940s. These are just two examples from linear algebra but I would also hope there are interesting historical examples using multiple linear regression and statistics too. With your teaching style it would be very informative and inspire more people to get into math at a deeper level. Thanks either way, your efforts are much appreciated! :)

Thank you for this well explained video, truly help me to understand multiple regression. BAM!

[blythe.]

most of the instructors of resources would always divide simple linear regression and multiple linear regression, not gonna lie that just makes everything more complicated!! so super appreciated how you put all of these concepts in the simplest way to digest, and they are really, not a big deal LOL

This visualisation of multiple regression with the green 3d line that you are using is really nicely done, these kind of visual aides really help us newbie students with the intuition of these concepts the first time they see them. I am using the Woolridge textbook on econometrics and this video is better done in about a fifth the amount of time. Just thought you would like to know that your videos are greatly appreciated :)

Oh this was so helpful!, If only there was a video about the assumptions of multiple regression and interaction effects, stats is slowly killing me

[Kaaaaaaaam]

This is great. Can you expand on this by explaining why and how Multiple Regression, Hierarchical, and Step-wise Regression are different? I more or less know when to use one over the other, but your videos are really helping visualize and understand these principles.

Oh my god
Statistics seems too easy now after watching your videos 😲😲
I searched whole internet for such videos that explain concepts in simple and fuN wAy
FInally Youtube Algorithm after seeing my struggle 🤣Suggested me your video

Thanks a lot
Now I'll see the whole Playlist of statquest 🤪😎😎😎🤪
now i only require this part for my exams !!! 😁

Once Again THank YOu 🙌🔥🙌🙌🙌🙌😝

I didn't need to see the video to subscribe, you got me with that intro!

Up there with khan acadamy and 3blue one brown. Best machine learning and stats videos on youtube. Would love if there were exam style question and answer examples, like in khan acadamy, but I still seriously good. thank you very much for your videos

[sugarmoon]

Josh! Building a model to evaluate PV system performance and came across your videos. Love it!

[MeatballQQ]

Hi Josh,
Thank you for all of your videos so far. It's truly a great help.
I would like to know if you have made any videos for multiple regression with CATEGORICAL independent variables? I have some confusion of how to interpret the coefficients of such regression. Or maybe I just give you a simple example and you may give me a brief explanation.
Thank you very much again.
Quynh.

[feroci-tay]

This was expalined pretty well. Thanks.

[dvijeniya]

thanks for the super easy explanation. I appreciate your support.

Despite the annoying intro, this video was very helpful.

At around 4:20 of the video, you introduce this new F equation where we eliminate SS(mean) from the equation to compare the simple and multiple regressions directly to each other. At 4:50 of the video, you mention the difference in R^2 values between the simple and multiple regressions. The equation for R^2 = (SS(mean)-SS(fit))/SS(mean). Do we also have a new R^2 equation when comparing the simple and multiple regressions directly to each other? Or are we calculating 2 separate R^2 values and comparing them to each other? Thank you!

Hi. Awesome video.

Can you do one one multivariate analysis, Anova, covariates please? I had a hard time in uni understanding them. Thanks
