Heteroskedastic errors - example 1

[@mshara1]

Cool video. better than my expensive uni classes.

[@lsw1789]

IKR when your lecturer only explained this based on his worded PowerPoint slides

[@orderinchaos]

This is so relatable. I'm using this series of videos to teach me what I need to know for an assignment

[@r4ts311]

FINALLY something that helps intuition for those of us without an advanced mathematical background

[@vodkapuppy11]

Oh my god, you are a life saver!! I AM GOING TO PASS!!!

[@420sIpod]

Haha, don't think the university lecturer is making the least amount of money out of the whole population! But the video was very helpful.

[@hottea1]

lol true

[@zhulindizi]

This is very clear and easy to follow! I wish my course could use more examples like this!

[@raphaellebeau6368]

thank you so much, I just watched all your videos on heteroskedasticity, it's so clear! I'm gonna keep watching for multicolinearity, so helpful :)

[@woodland5325]

At the University of Manchester our course supposed worth thousands links all of your videos, as the lecturer knows that they are the best thing to understand econometrics.

[@Michelle930911]

you are the best! preparing for my diploma paper 3 (Yep, the one you have done before!)

[@vaig6799]

Gold mate. Clear to follow and understandable

[@AndreDidriksen]

Beautifully explained. Cheers

[@mehradghazanfaryan640]

best best teacher hope your wage increases as your viewers increasing too :)

[@xxxcleocielo]

just one question, why did my professor spend two lectures explaining something which can be clearly presented within 5 mins??

[@rashidi.]

In which university you are.

[@talebmahfoudh2425]

what happens if the error variance is nonconstant?

[@sharad5149]

Just to confirm it’s not 6to the power 2 right, that’s a Greek letter which is a constant ? Correct? How do we find that value of the constant do we have the do the OLS test in stata?

[@josemedina5486]

I congratulate you for been so clear and thanks. José medina p.

[@josephmiller6876]

Are heterogeneity and heteroskasticity the same thing? My econometrics lecturer says I need to know how to estimate and test for "heterogenous effects".

[@MayaMaya-rb5wc]

Hi Joseph, no heteroskedasticity and heterogeneity are not the same things. Not knowing your model, I can only assume that heterogeneous effects are like individual effects. For example, does your gender/education/family status have an effect on your dependent variable.

[@vram11]

Thank you... Clear and to the point....

[@ThePho4life]

thank you so much for all your help, do you have a video showing how to proof the expected value of the estimators are unbiased?

[@yutonglu5150]

Thank you sooooooooo much

[@iskandariyah20]

haha definitely agree with Ryan Bull Lol

[@kkkailou]

life saver thanks

[@klara3089]

Thank you!!

[@milespender4831]

Lin-e-ah not lin-ear please :(

[@rashidi.]

Ya Allah, it's too easy
