Ordinary Least Squares Estimators - derivation in matrix form - part 1

This video provides a derivation of the form of ordinary least squares estimators, using the matrix notation of econometrics. Check out ben-lambert.com/econometrics-... for course materials, and information regarding updates on each of the courses. Quite excitingly (for me at least), I am about to publish a whole series of new videos on Bayesian statistics on youtube. See here for information: ben-lambert.com/bayesian/ Accompanying this series, there will be a book: www.amazon.co.uk/gp/product/1...

This whole channel has saved my degree. Thank you very much Ben.

Really appreciating the course. Thank you for sharing your deep knowledge of econometrics.

[@ronzo0]

Thanks so much! :D The matrix derivation of OLS has been annoying me for the past few weeks, but this video really clears it up

[@georgeikennaewah-uche4477]

Thank you so much! My lecturer only explains her econometrics with matrices and I was lost as I only knew the summation form. I am very grateful for this.

[@Majagarbulinska]

this is extremely helpful. thank you Ben

Hi
I am a PhD Economics Student. Our instructor for first PhD econometric course have us watch these videos as a class requirement tasks.

[@3foss191]

Ahahaha, only you has all the reponses to my econometric's question. I'm addicted to your smart videos. thks a lot

[@emresahindance]

great video, thanks

[@kanboify]

it is a fantastic video !!!!

[@vaibhavsingh1049]

Thank You.

[@daweili9843]

though demands some elementary backgrounds for viewers your explanation is great!

[@achilleasmanousakis4622]

thank you!

[@dhawals9176]

great lecture. Off topic. What is the setup you use to write on the screen?

[@carlosp4250]

Videaso gracias!

[@endrity]

Nice vids mate!

[@chandnibhudia624]

thank you soooooooooooooooooo much!!! i dont suppose you have any videos on the neyman pearson lemma??
kind regards

[@SpartacanUsuals]

Hi, thanks for your message and kind words. I don't have any videos on that subject yet, although I have added this to my list! Best, Ben

[@oskarg4270]

Whats 10 times ten again?

[@zoolander0700]

You're a god

[@-Geo-Man-]

good job

[@lilizhang9440]

so whats the estimation of alpha hat?

[@ericw2859]

life saver

[@abubakarqahwe8754]

where is alpha when you creating this new formula y=xb+u

[@robenwu620]

why it is so named "ordinary"?

[@vinuthomas2814]

Why is it that there is no matrix equivalent for the alpha portion of the original equation?

[@abubakarqahwe8754]

yes even me I confused that

[@rakoonberry7879]

There is. The first column of X is full of 1s and the first number in the β-vector is the alpha.

[@Max-cs1dn]

Beta hat? Pizzahut.
