Powerpoint is crisp. Explanation very clear. Straight to the point. What a teacher!
LETS GO JOSHUA! ABSOLUTE UNIT, giving us what we need
I didn’t understand my professor’s lecture and not even when a friend tutored me. Thank you for explaining this in such a calm and easy way
how a proper teacher should be. Speaks clearly, information is clear, every step is explained and all abbreviations are explained instead of plopped onto a useless powerpoint without any explanation.

Excellent stuff!
Very informative.Thank you.I can answer now my case study about here.😭😀
You are really good.
Thank you, God Bless.
Great video and thanks for the explanation. How can I get success value when failure probability and failure value is given?
Can you clarify?
u r excellent... bro. Thank you
Subscribed. You're awesome.
thankyou so much.. god bless you 😇😇
Thank you so much sir! I really understand your example than my teacher 😂😂
You are a legend!
Thanks Josh. i've had a look through the comments and no one has asked about the consultant's fee. In the real world you'd be given a currency for the fee, but "3.5" at the end seems like some proportional conversion was done. Can you explain that and how that can be applied to R/L?
The idea is that all the values are in the same unit/currency. Whether you slap thousands or millions of dollars on those numbers, the concept holds true.
Saved my life!!
Please, What to we do if we don’t have the probability of having a positive or negative repport? We have conditional probabilities ( Our prior probabilities are just probability of growth and probability of decline)
You might have to calculate them. See if this helps: ruclips.net/video/FpKiHpYnY_I/видео.html
How would you calculate the equivalence of the consultant's fee? I don't think it's the actual fee, is it?
Very Helpful!
This is great stuff
thank you so much!!
thank you so much.it was hepful
This is so helpful..but please tell me, can EVSI be negative?
Yes. EVSI can be negative. It is possible to do worse with a consultant than without.
@@joshemman briiliant! Thanks for the speedy response.Much appreciated!
what happens if the EVS of dont hire is greater than if to hire, would it still be calculated as 6.8268 or would it be negative EVSI, in which case the decision would be to not hire?
thanks joshua...
Hi Joshua,
First great videos!!!
Second, I would like to ask you something on the video above.
Assume we hired the consultant and he recommended negative report,
Now we have another consultant who say he can recommend about better decision,
What is the EVPI?
Would it be changed if the consultant recommended positive report?
Thanks in advance!!!
I'm sorry, I would need to see the full scenario to better answer this. However, EVPI does not depend on consultant recommendations.
Assume we hired the consultant named Adam and he recommended negative report,
Now we have another consultant Rob who say he can recommend better decision for the negative report that Adam recommended (like he has inside information) ,
What is the EVPI for the negative report recomend?
Would it be changed (the EVPI) if the consultant Adam recommended positive report?
Hope it's more clear
Can you make another video to explain how to perform graphical sensitivity to P(high) ?
Excellent..
