well explained.
we cannot see where you are pointing
This is awesome presentation. The intro is very elaborate, very enriching indeed. Accommodating baby like learners. Thanks Don.
You make learning to be much better and fun. Everyone says you are the best and i agree 💯
Amazing explanation 👍👍👍
Very informative, thank you!
Well explained 👍
Good stuff sir
Well explained
U 1 is wrong V2 is 3 -1+3 ≠ 1 It should be -2 -2+3= 1
Thanks for pointing out. Correction is at 13.30 of the same video.
What happens if there are 2 rows with the max allocations? Will you choose one random and give it to be 0?
Yes, break ties randomly.
Subscribed!
very clear thank you sir
Great video. You are awesome. Thank you so much
Here is the simple linear regression case: ruclips.net/video/vYnmvGMXE6I/видео.html . This can be extended to more than 2 independent variables as along as we have the right tools to solve the simultaneous equations
Well explained thank you
Thank you
this is perfectly presented, thanks
hey, when you have 3 independent variables then in the multiple linear regression the coefficients are 4 how do you solve for beta 3?
thanks very much
wish we could see the illustrations as you present.
very helpful
Hello sir, please enlighten on how to get confidence interval for coefficient of beta
The same as the case of CI for mean but replace x-bar with the beta in question. Here you use standard errors of that beta- this is usually part of standard computer output in regression analysis but can be also be calculated by hand. I have done some videos on Inference for regression coefficients - check them out.
I was struggling..this is well explained .Thanks.
FUCK, I CAN'T UNDERSTAND YOUUUUUUU!!
Thanks alot.Have learnt something
Thank you
simple and beautiful way of teaching.
Well illustrated Don.
Thanks so much,I have understand
preparing for this unit May-August
not the don, the mafia king of stats
What about standard error for Three variables
I appreciate your help. You have deep knowledge and precise explanation. I havent seen anyone to upload multiple linear expression with two independent parameters except you. you have easy my work. my work contains more than three i ndependent patrameter but now easy. I have a question, How can I determine the trend and the error? thank you
Glad it was helpful!
So helpful.thanks lec
Simply the 👌
Thank you Don
Thank you Sir
You're welcome.
very well explained
the texbook did not make sense at all but your video really helped me out , thank you so much
My brother. I am in Marketing but enjoy your videos 🤝
Thank you my sister.
Till now, I was thinking that only Matrix method exits for Multi linear regression problem. Thank you Professor for this method which is very easy to understand and solve
Thank your sir for your comment and compliment. I'm humbled. For more videos see www.youtube.com/@StatsDon
Thanks
Mwalimu,You are masterpiece. THANKS
I appreciate your service sir
Thank you so much
You are welcome.
thanks sir, learnt something,how will you get r using the calculator
Use REG (linear) mode if you're using CASIO FX82MS. Enter the pairs of values (x,y) separated by comma. After typing every pair, press M+. When done entering the data, use S-VAR to locate "r"- you need to use the right navigation key on your calculator to find this and other measures.
Is this really same as y=a+bx?
Yes, see 7:12 - 7:14. The convention is to use betas instead of "a" and 'b"
Always try to control background noise . The kid sounds to be in need of help . Anyway this is an amazing presentation with too much advertisements.
Thanks for the compliment and advice. Well taken.
sir,how will you get the values via the calculator explain please thanks
Use MODE: STAT---->a+bx or REG---->Lin, depending on your calculator.
@@TheStatsDon thanks identified it...please am looking for on how you will insert the values of x and y ...so that you cant easily get £x,£y,£xy,£x(squared) and £y (squared)
@@hazzani678 see my earlier explanation. To get those summations use S-SUM instead of S-VAR.
