You seriously have an amazing straight to the point teaching style!
As a Stats Professor, I can say that your videos are amazing! Great work
Thanks for leaving note, Linda.
You are the Angel that God has sent me to pass my exam!!! after 5 times failures I thought I would never pass it !!!
Your explanations are so clear and straight to the point. YOU ARE THE BEST…
I salute you sir, you have saved a lot of hard studying for us !!! God bless you sir!!!
You are no 1 teacher , i was struggled last 1week for CMA preparation, now i came to understand it. excellent teaching....
Oh my god Ive been struggling with this for so long. You made it so clear lol Ive been overthinking this so much. Thank you very much sir :)
Great video man, I´m starting my MBA and this helps a lot, I´ll suscribe to your channel
Best explanation, clear, understood.Thank YOU!!!!
Thank you very much for your presence
thank you! shortly and precisely explained!
Thank you for your efforts.
Great full preparation ❤
You're absolute angel that help me pass
You are brilliant Sir. Thank you so much!
Joshua, you are the man!
my homework makes sense now Thank You!!!!!!!!!!!!
You are really a Great teacher ☺️
Love from Pakistan ❤
Thanks, Mahan. 🇨🇦❤️ 🇵🇰
@@joshemman you welcome 🤗
you're an amazing person, thanks!
You are awesome. Your videos help so much!
Can I ask, in your previous video you stated that the EVwPI is calculated by taking the best values from each state of natures and taking their sum from the equation. However, in this video, you are using the lowest values from each state of nature. Do both these methods lead to the same answer? Or is there a mistake somewhere.... Thanks!
Note that the best cost is the lowest.
With profit you use the highest value because you want to maximize however with cost you use the lowest value because you want to spend less. Profit you want to gain more so you work in mind with the highest figures. Cost you want to pay less so you work with the lowest figures. hope that helps.
Thank you. I was struggling with this matter
Thanks! You help me a lot!
hi, can you pleaaseee do a video on constructing the risk profile of the expected values of decisions? I dont understand how to do it. Really need your help because your videos explain everything so easily.
Thank you for saving my Uni mod!
Thank you so much for your videos sir.. so clear and easy to understand!! I appreciate this so much! (:
How do you calculate probability of each state of nature?
Hello sir, I want to ask a question again, what s the difference between a perfect forecast and the expected value of perfect information, this is from questions in my textbook
(e) How much is a perfect forecast of the demand worth?
(g)what is the expected value of perfect information in this situation?
i tho that question (g) is asking about EVPI but what about question (e) i need your help sir T.T
thanks so much u are God sent
God Bless you sir
needed! thank you!
thanks very much joshua
Good work, add tutorials on game theory pliz
Can you please explain value of imperfect information urgently?
Please, is expected utility the same as value for perfect information? Thank you.I appreciate your reply.
Thank u so much sir
Thank you so muuuch
How to calculate perfect forecast of demand worth?
Sorry why is thr smallest value of the respective states , the EVPI ?
Because these are costs. The smallest is the best.
For profits, see ruclips.net/video/tbv9E9D2BRQ/видео.html
Hi, what if the lowest value in each category is 0? Do you use 0 or the next lowest number?
If they are costs, the lower the better.
@@joshemman sir how do you get the probability of each state of nature?
In other videos for EVwoPl they choose the maximum EMV
This video is about costs. For costs, the smaller the better.
Good video👍
how to identify the probability of each state of nature?
The probabilities are usually given. If they are not given, you cannot calculate expected values.
Hello Joshua, what happens if there is same value under the same state of nature, but the probability of each of these value is different? which value shall i pick to be calculated in the formula? You reply will be appreciated.
The method explained here works for decision problems that can be organized into a payoff table so that each state of nature has only one probability.
I'm guessing you cannot organize the scenario you just mentioned in a payoff table. You can send me the problem to take a look.
@@joshemman Thank you for your reply, i think i understood what you meant. I have already resolved my problem. Thank you Joshua. You are really helpful. : )
From where did you get probability value...??? I dont understand. I have 1hrs please tell
They are usually given. If they're not given, then you should not be using this approach.
@@joshemman ok
Calculate payoff matrix for bitcoin
Thank you sir 🙇
GOATED
😆👍
How To Find Probability please reply for this example
If probability is not given, then you're not calculating Expected Values.
@@joshemman How To find it Please Help me
how can I find the probability ?
It is usually given.
❤
Sir can u teach integration
Yes, I can teach integration. But I do not have audience for it.
K sir
Can I have your email please ?

did you figure it out?
