I discovered this channel in youtube search and guess what it burnt all my frustration and I love the way to make people understand topic in this video!
An Amazing video and explanation. All these other videos only said points on the probability density function are likelihood but it didn't make any sense to me. the way you explained it cleared everything.
Great video! I'm just curious: When you say "we don't know which universe we're in," is this just another way of saying, "we don't know the probability distribution of the coin"?
Amazing, if i got correctly its like In probability, we start with the whole and then delve into the details, but in likelyhood, we begin with the details and then move to the whole.
Yup, in probability we start with the situation/universe/parameter and find the probability of outcomes. With likelihood, we start with the outcomes and try to figure out the situation/universe/parameters!
Lately I've been introducing LRT, or tests in general, to my coworkers like "I would bet you with 1:20 odds that this coin is rigged, would you take this bet?"
No worries, Martin - you only really need to know what "likelihood" is if you're doing advanced statistics stuff anyways. In everyday language, these words mean the same thing, and even in statistics, they are really not so different!
A Very nice explanation. We poor experimental physicists (and any other scientists whose discipline is base on observations) deal almost exclusively with likelihoods - we use observations to draw conclusions about the (a priori unknown) properties on the actual universe. Theoretical physicists, OTOH, postulate those properties and calculate probabilities of what we _should_ observe. Then we compare the two.
I’ve had 7 statistics courses at the graduate level, and no one has ever explained what likelihood is.
Thank you.
Why does this reminds me of StatQuest?
We both use Keynote to make the slides :)
I was thinking the sameee 😂
loving it too ❤

Clearly explained the complex concept.
By God what an absolutely amazing video.

Thank you! So glad you found it helpful!
Great video
Great explanation! Naver really what is the difference between these two.
noice...the graphics helped a lot
Even if the coin is not fair the probabilities still adds up to one.
That is very true! Likelihoods of a single outcome under multiple probability distributions, however, do not add up to one.
Unless it lands on it side

Yes, exactly!
Love your videos!!!
Recommend me good books in mathematical stats, please!
Thank you! My personal favorite is the classic Casella & Berger!
The single word 'universe' made it all clear! Thank you for a neat perspective :)

"No sir, I don't gamble. (alpha = 0)"
Can you do coupling some time? I know it's important to the earth mover problem.
I don't know much about it, sorry!
@@briangreco2718 Ok me neither :)
Incredible explanation, clearest I found out there, 🎉
Thank you, glad you liked it!
pr ( getting a head tossing a fair coin ) = 0.5 or a half
I am glad I did not major in statistics....Still don't get it....

The best explanation on Likelihood ever!!
Thanks Terry!
I once flipped a nickel onto the floor, near a wall. It bounced off the floor, one-hopped the wall, and landed on the EDGE of the nickel.
Such acts of God are being the tools of probability.
