Multiple Regression, Clearly Explained!!!

This StatQuest shows how the exact same principles from "simple" linear regression also apply multiple regression. At the end, I show how to test if a multiple regression is better than a simple regression.

If you'd like to support StatQuest, please consider...
...or...

...buy my book, a study guide, a t-shirt or hoodie, or a song from the StatQuest store...

...or just donating to StatQuest!

Lastly, if you want to keep up with me as I research and create new StatQuests, follow me on twitter:

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)

1 million subscribers and John still takes the time to respond to every comment on his videos. Thank you for your help with understanding my assignments!

Universities should just play your course videos in classes instead of making failed attempts in teaching

[meri_mory]

I'm doing a class presentation on this in graduate school so thank you so much for the help! 😭

If we used R squared and p-values to see if the tail length is relevant, what the reason for calculating the F value. What purpose does the F value play here?

[Mostusernamesaretakn]

We need a StatQuest of the FWL theorem! 🙏🏻

[gametech]

Please make a statquest on multivariate linear regression

Hi Josh, Do you have any video about multicollinearity and Variance inflation factor?

[dward]

If p_multiple > 3, do we generate several F values comparing to simple regressions for each other variable?
eg. multiple regression for body length vs. mouse weight, tail length, wheel time
would we have to compare: 
- simple model of body length vs mouse weight and multiple model of body length vs mouse weight, tail length, wheel time
- simple model of body length vs tail length and multiple model of body length vs mouse weight, tail length, wheel time
- simple model of body length vs wheel time and multiple model of body length vs mouse weight, tail length, wheel time

thanks for another excellent video

is there any video for the degree of freedom please? i searched a lot of it but still don’t quite understand why each parameter in regression will “steal” a degree

[nilanjana]

please make a video on linear regression assumption.

[praneethduggirala]

what would be the n value there in multivariate - 3?

[TheBlueFluidBreathe]

Bro you should have a video only about F-statistic on regressions, you did good explaining but a bit out of the topic.. thank you very much anyway

I felt like I was watching cartoon network lite, not fun when your learning

[lucutes]

oof this one wasn't it. I suggest you to add real task examples while applying the theory you've covered.
