David I can't find a PDF file for ET 1 and 3 on the site Frank

David P(A|M)P(M) = (100/300)*(300/500) = 100/500 is the tree using the notation in Gujarati 100/300 is P(B/A). Not P(A/B) which is what you have above ,joint probability P(AB) = P(A|B)P(A). Also when you switch to A's and M's it is the opposite notion of Gujarati's notation. A=Male and...

I am stuck here P(A/B) P(AB)/P(B) but P(A) P(B) =.6*.32 or .192 is not P(AB) = P(A)*P(B)

Hi David, I am having problems understanding some of the formulas in Gujarati chapter 2 on page 30. 2.7 page 30 P(A/B)= P(AB)/P(B) for me this always comes out to P(A) When he explains it he refers to figure 2-1 ( c ) but then in the explanation I don’t think P(AB) is the numerator...

Hi David, Please e mail me when the early bird is ready. Frank

David, Should we review these?

David, I cannot follow your spread sheet for the solution here. The spread sheets are great but sometimes it is hard to move from cell to cell to figure out what has been done what has been done. Frank

I am sorry David. It is the Variance formulas on page 2 and 4 Frank

David, Can you explain the difference between the variance formulas on page 1 of 79 and page 3 of 79 OF YOUR FORMULA SHEET. I think that if I get that I will be ok

David, I see how you are doing it. Why do we not use means sum of squared deviations in this calculation? Frank

Hi David Variance = E(X^2) - [E(X)]^2. For a coin, E(X^2) = 0.5 and E(X) = 0.5, so its variance is 0.25. Since two coins are independent, their variance = 0.25 + 0.25 = 0.5. Finally, the Variance (5*X) = 5^2*Variance(X). In this case, variance = (25)*0.25 = 6.25 How is E(X^2) and E(x)...

PS..The word is wording of the problem

David I know how to calculate a standard Dev but the working in this question has me confused. I did not know where to start Frank

David In the market section you say that the geometric average taked into account 1/2 the SD How does that work. The formular is to multiply all the factors together and raise them to the 1/n power. less 1 Frank

I Thought we went through Jorion fast. Are you going to do some mini screencast?

In this section we say that Gold is a diversifyable risk for the investor . It is also a systematic risk for the firm. So the investor in this case can also diversify systematic risk. I just want to be sure I understand this

David, In your slider you say that reputation is not part of OR but I see it a lot in Linda Allens reading
