Introduction to residuals and least squares regression

i still don’t get it :/ you lost me at weight =m(height)+b what does that mean!! please am i like severely mentally i’ll and can’t understand rules or was it not directly explained why we suddenly wrote that like the cause not even why but the why for the why

khanacademy is the G.O.A.T.

As a freshie in HS I’m watching this right before midterms and BOY HAS THIS HELPED ME A BIT

Even though these videos are getting fairly old now I still think they are amongst some of the best on the Internet!

Thank you, this was very very helpful

Always Great Sal , Thanks

I can literally NEVER understand ANYTHING from their math videos and everyone is saying how simple it is what??

what is difference between residuals and bias?

You taught me what i needed to know in 6 minutes and my math teacher couldnt in 2 months

thank you!

which software are you using to create all this?

Why are both correlation coefficient and residual "r"?? Isn't that confusing?

can you please share the link of the next video? i am not able to find it.

I still do not understand the reason why my teachers don't use these as an explanation video instead of something else.

Is there a way to watch these in the correct order? :D

in less than 8 mins, you taught me what my teacher couldn't in a whole semester. Thank you sooooo much, sensei!

Better than my university lecturer.

why we are squaring the residuals ?? i case of negative values if we upply mod then it will become positive then what the case with the squares of the residuals

Thanks for the useful video. What software,platform you are using for writing is it ipad ?

Nice bro

Great video THANKS!!!

Please make the board on light mode.. The writings on the board aren't visible

Reviewing to prepare for my interview tomorrow 😅

still confused. its too fast for me

Thanks for this guide

Great video! Very interesting... what software are you using to draw the lines? It seems very flexible and effective.

Thank you, this explanation makes the topic much easier to understand!

It is very useful

Great video...good explaination👍🏻

you forgot to mention about unobservable and observable values

midterms 😣!

iv'e been searching everywhere and watching videos for an unambiguous explanation of OLS. Finally someone explains properly

Thank you.

where my precalculus gang

I owe you my degree. Can you be my dad ?

HT & WT MEAN NOTHING! IT'S ALL ABOUT AGE, BODY MUSCLE MASS AND BODY SHAPE!

i somehow get more confused listening to you hop around so much. please be more organized

Sal does good in the video, he always does, but i don't know why his voice annoys the heck out of me!

seriously I have been following every single video of yours. such great help. so much easier to understand than the lectures and so much fun!!

How do you calculate the slope "m" in a non cartesian coordinate system ? (non ortho-regular system)

fantastic explanation

How do you do it when you start with a table of values?

This helped me understanding linear regression as I am studying machine learning

thanks I actually have a better understanding now

First, THANKS.
Second, please resolve 2 issues:
1. Why is the line named Regression Line. From simple English language, I understand the Regression is the opposite of Progression. There should be some thought behind statisticians choosing this word to-draw-a-line-to represent-data. What's that reason?
2. For certain reason, I'm supposed to learn the Partial Least Squares Regression. Importantly, I don't have a background in Statistics. I'm finding it difficult to chart a conceptual-rung-of-ladder to achieve that goal. Can you please guide me to a series of URLs to learn PLS starting from basics through appreciating the concept nicely? This is my need and I'd be grateful if you address it.
Thanks and best regards.
