Multivariate Normal Distribution | Probabilities

[@JimBob1937]

This is considerably more straight forward than what I was taught. Thanks!

[@ytspacedementia]

Brilliant explanation, thank you!

[@phitara4023]

Excellent! Straight forward to the point. Thank you

[@vivekkds287]

Very quick video and liked it a lot. no lagging only solving.

[@kitengeedwardmakau603]

Quite elaborate and easy to understand. Good job.

[@gabrielparada8901]

Great video!

[@evansm.k9973]

thank you.. have learnt so much. please do more videos on conditional mean and variance of multivariate distribution given mean vector and covariance matrix.

[@mstat.academy5142]

Thanks so much .plz upload more numerical problems.we are gating more benefits by your great efforts.

[@nitigyajoshi4658]

Thanks a lot sister. Very helpful tutorial.

[@cspan1993]

wow amazing video!

[@timz2917]

Finally a tutorial that doesnt teach me like a 3rd grader

[@salih3145]

Thanks. Can you please tell why haven't you divided by square root of n to normilize?

[@UbaidKhan-ro7tr]

Thanks for your contribution.

[@raceregos]

I guess I fell in love to your relaxing voice.

[@yichenqian405]

Great!

[@ashwinibarve6389]

Very nice explanation mam

[@alejandracabrera2160]

thank you

[@kcroy]

Your Video was super helpful. Thanks

[@anitaalado2291]

Good work done. kindly, solve more questions on mv data analysis your videos are very helpful.

[@diazfikryag4864]

Thank u so muchhh... Really helping me

3:36 she said it. she said mewtwo!

[@jonahmarlow3991]

Gotta catch em all!

[@realcirno1750]

Very helpful

[@darwinvinci7744]

Thank you. Also, where is c?

[@nickzadpratama7406]

Thank you...

[@sanaullahkhan3992]

Why u can't discuss its expectation value and variance?? I didn't see any video which briefly discuss other parameters in their example.

[@Skulltroxx]

why is p(z-0.5)? thats the only confusion I've come across in the entire video...

[@Jayveersinh_Raj]

It is because of symmetry that from -inf to -0.5 is equal in are to 0.5 to +inf

[@Skulltroxx]

@@Jayveersinh_Raj got it, thanks

[@mikehaddad2037]

A mistake was done in your calculation on the multiplication of the first matrix one at row one column three with matrix two at row 2 column 3 the answer of the multiplication should be 10 you had six.

[@jumaciry831]

I think the answer for part (a) should be 0.8085 and not 0.3085 because it's 1- P(z>0.5)= 1- 0.1915= 0.8085. Is this correct?

[@jeffery_tang]

no it's 1-0.69

[@JimBob1937]

She looked up the value to infinite CDF output indirectly by a negative, but if you don't have a CDF table that has negative z values, or if you are using something like Matlab's normcdf function, it is going from negative infinite to the value. In this case that is a cumulative probability of 0.69, which is the probability that the value is < 6, thus for > 6 you can take 1 (the sum total probability) - 0.69, which is the probability left over, aka, > 6. This makes the final answer ~ 0.31. May also want to check how you got 0.1915, as it does not equal that for 0.5 either summation direction.

[@anitaalado2291]

@Juma Ciry....because she used the negative when you pick your calculator, go-to mode then 3, go-to AC shift+1 then, press 5 then 1 then you enter the negative. p(-0.5)=0.30854. yes, this is how you get the value. So, if it is already a less-than probability, just enter the value without negating it. thank you

[@amirzadeh]

Great video...Just please do not use that eraser many times!

[@raza2594]

Probabilities are killing me with improbable certainty...

[@excelmaestro9798]

The probability that statistics is a bit over my head =1 🥺

[@Dilz13]

wow

[@piyalikarmakar5979]

How to get .3085??

[@anitaalado2291]

you can use a calculator to get it. go-to mode then 3, go-to AC shift+1 then, press 5 then 1 then you enter the negative. p(-0.5)=0.30854. yes, this is how you get the value. So, if it is already a less-than probability, just enter the value without negating it. thank you 1

[@Jayveersinh_Raj]

There is a mistake it should be 20Cov(X2,X3), 5*4=20

Her voice is just gorgeous, healing my heart broken by the god damn mathematics
