    Buying a fraction of share in reality ?

    many times I see in option pricing,for example, buying 0.967 shares of stock ? In reality, can we really buy that amount of stock ? instead of buying 1 shares of stock. :Confused:

    According to http://www.soa.org/files/pdf/edu-fsa-mod-books.pdf , The Essentials of Risk Management is required for operational risk module.

    or it's just changed recently ?

    my question is I should completely read the book before taking the module or read the book...

    MLC Sample 9

    I don't understand the solution provided. Why doesn't SOA add the case that an express arrive before a local sine it holds the condition asked ?
    Could anyone help clarify this to me ? :wacko:

    MLC Sample 06

    I don't understand why the latter of APV Premiums is 20E40*Zigma(kE60*1000vqx)

    I think it should be 20E40*Zigma(1000vqx*(PMFx)) .

    which ,in this case, PMFx = kPx*Qx+k .

    so the result is...

    Some of the cal3 and your cal4 is my cal 3. For exam P, partial differentiation and multiple integrals (especially double integral) are useful, the others not, I think.

    No,we should integrate x^2*fx^2(x')dx

    Note that fx^2(x) means PDF of x^2 and x in the bracket just means a real number coming from x'=x^2

    Perhaps, we can find PDF of x^2 from MGF.
  10. I don't believe the definition since I think it's...

    I don't believe the definition since I think it's more reasonable to use PDF of g(x) for E[g(x)]. This is the same reason that we use PDFx for E[X] , we don't use PDFy for E[X] although Y probably...

    I mean why we use E[g(x)]= integral of g(x)*PDFx dx (PDFx= PDF of x = fx(x))

    instead of E[g(x)]= integral of g(x)*PDFg(x) dx (PDFg(x)= PDF of g(x)= fg(x)(x))

    Note that fg(x)(x) , g(x) is just...
  12. Why we have to use PDFx to find E[g(X)] instead of PDFg(x).

    According the topic, I can't find any reason. Could anyone help me verify this ? :wacko:

    Poisson parameter = integration of 2dt from 0 to 60 (minute)

    I'm starting to understand the context "average"; they refer to the average of the total range instead of the average per unit :wink:

    Daniel Poisson Processes's Study Note ?

    In page4, line 4-5 , why does he conclude when integrating a Poisson process's rate function over an interval, we will get the average number of events in that interval.

    First,you have to understand what is the meaning of a(3)=(1+0.03(5-2)^2) .
    It means that if you have 1$ at t=0 , then you have a(3) at t=3. It doesn't imply anything else about t=2 and t=5.

    I think it's not simple interest since a(t) of simple interest is linear ,not t^2
