    Hi Ken, I didnt dislike it someone else must have done. Yeah Id appreciate that. thanks
  2. Calculating portfolio risk with

    Ultimately yes. I have already constructed the dependence between 2 stock payoffs using copula but Im not sure how to calculate the standard deviation. That's where Im stuck at. I also need to choose the best weights to invest in each stock. Thanks
  3. Calculating portfolio risk with

    Hello all, I need help. Im writing a diploma research and Im stuck at one point. So the story is as follows: I plan to create a portfolio of 2(for simplicity) assets with Markowitz portfolio selection model which takes linear dependency between assets into consideration. I did that thing and...
  4. C++ vs C#

    Interesting...
  5. C++ Book

    Not math focused book right? I already started reading what you recommended previously. It also seems very good since it explains the constructs of C++ in math language. Good one. Thanks
  6. Simpson Integral Algorithm

    It depends. You cannot derive the exact formula guiding you to select the n. Its depended on the scale of the function. There will be need to manually choose n for each function.
  7. American Options pricing

    General question: Is there an only way to price an American Option?
  8. Paul Willmot on quantitative finance

    Completely agree. I have defined some simulations algorithms in C++ and its much more effective in the same manner as Willmot uses and much faster in the same method construction. But you can easily translate the VBA code into the C++ code. The methodology is the same, just the syntax is different.
  9. C++ Book

    Thank you very much
  10. C++ Book

    Thank you guys for your attention. I already ordered the book you recommended Tsotne. I'll try to follow that book and take a look at "Absolute C++/Problem Solving with C++ by Walter Savitch" also(Its seems very big in size, i'm currently downloading) As I read the description of the C++ for...

  13. Method Overloading

    Thank you Tsotne. I need to define the MMult (matrix multiplication) method in the same manner, now thinking of the algorithm. Any ideas? I have already taken your advice into account to cast them explicitly from the caller's scope
  14. C++ vs C#

    Why do recruiters ever prefer C++ over C#? As I read most of job requirements in this field C++ is being required in the vast majority of these cases. Can I replace C++ by knowing C#? Or it cannot be altered. Actually what I'm asking is if I can send the application to a job requiring C++ when I...
  15. Investments 7th VS 8th

    Actually there are several reasons to update the book every year even if it doesn't contain significant improvement: 1) To keep up with the sales rate in order to maintain reputation and popularity. 2) To increase the revenue by charging higher price even if the book is basically the same as...
  16. Programming innocence - just say "Fcuk it"

    This is exactly what Ive been thinking about over the recent days. I started creating new mathematical libraries and not everything is perfect at this point. I just know that ill modify the code when I learn new ways to deal with the details involved. Actually I never fear what other programmers...
  17. Investments 7th VS 8th

    That's why I asked this question. I think these books are just the replications of the previous editions. Marketing strategy : to publish new books every year or two. How can an investments book be much different from the previous one. Its not a "Harry Potter" book to invent a new tale or some...
  18. Investments 7th VS 8th

    Hello! I need your opinions about the "Investments" books of Bodie-Kane-Marcus. At university I have studied "Investments 7th edition" and it was really a great book. And i wonder if something is improved significantly in 8th edition and if so what?. As I saw there are more talks about the...

  28. Facebook's Mark Zuckerberg is Time's 2010 Person of the Year

    Julian Assange is kinda oppressed from the point of Facebook success. All in all, we have 2 choices: 1) To admire a person who has a lot of influence and connection in IT society and can tackle things around easily and 2) To honor man who came up with an idea to invent something revolutionary...
  29. HyperGeometric Distribution

    Hi Can anyone tell me what are the mean and variance of hypergeometric probability distribution?? Thank you
  30. Bernulli to Binomial

    Hello! I need some help. As we know binomial distribution is nothing more than several times repeated bernulli random experiment. Bernulli random experiment has 2 outcomes: 0 and 1. So X = 0; 1. In case of Binomial model we have several Xs. Xi = X1 + X2 + ... +Xn. And its expectation and...
  31. Variance calculation

    So it comes out that if we let sigmaS/S = X Then V(X^4) = E[(X^4-3)^2] = E(X^8-6X^4 +9) = Sum(x^8P(x)) - 6Sum(x^4P(x)) + 9 Wrong oops
  32. Variance calculation

    Hello Friends! I need urgent help. Got a midterm exam this evening. So the problem is: Assume that deltaS/S has normal distribution with mean of zero and variance sigma^2. Calculate variance of random variable (deltaS/S)^2. Thank you very much

  35. Prob. Distribution

    I would send you a family of distributions u might find useful if u have skype or yahoo or mail where i can send. By the way, when evaluating financial data that can logically be thought of as exposed to large tails be careful in using modified logistic distribution for continuous X-s. ;) Tails...
  36. Prob. Distribution

    U can make the normal distribution tails thinner if you want...and add skewness and kurtosis as desired(of course by taking certain restrictions into consideration). You make median of the data more or less in value (by adding it) than mean creating a positive or negative skewness. If you want...
  37. Max-Min-Root algorithms

    Thank you very much Daniel. Actually Im a C# user, could you recommend something similar for C# (i mean the PDF). Focused on mathematical programming. Thanks 1000000 times
  38. Max-Min-Root algorithms

    Hello! I wonder which is the best algorithms to find the max-min or root(s) of a function... I have developed a code which passes through the all points of the function in a very big range and chooses if the value is max, min or equal to 0. So it takes very long time to get the value. What...
  39. VAR methods PCA vs FA

    I mean the explanatory factor analysis... That gives the latent factors given the set of some observed ones...
  40. VAR methods PCA vs FA

    Hello everyone! I have a question regarding the choice between the Principal Component Analysis and Factor Model methods. PCA's main focus is the diagonal terms in covariance matrix and FA model concentrates on off-diagonal terms. Everything in calculation of both model is clear and...
  41. Risk Calculation

    I dont think the question is asked correctly. There is no area in C++ concentrating on Risk calculation. U have to know the C++ language to calculate anything u want. It would be easier to tell u which areas u dont have to concentrate for example ( graphic design, web applications, etc) But i...
  42. Not scoring well on GRE

    I have the same problem, Im good at more advanced math but not at standardized tests. I think your main problem(as mine) is that you are concentrated in technical math, meaning that you can conduct complex mathematical calculations but cannot focus on simple problem or cannot mobilize your...

  46. C++ prerequisites

    I can give you the whole basic course book if you want it? See my skype and contact me if you get interested.
  47. Really basic calculus book

    I don't think that an elementary book will help you become a good quant. Quants deal with complex mathematics and invent their own models. I would advice a Barnet/Ziegler/Byleen business Calculus. It is very helpful for starters
  48. Early Financial C++

    Well then I think that you should before improve your math skills. If you go on searching for as you said "simpler financial program" then it makes you just have fun again not concerned with professional accomplishment. The reason why I give you this advice is that there are some kind of...
  49. Early Financial C++

    Aha, now that's clear. The best way would be to have studied the subjects you want to implement and C++ itself simultaneously but that's not a big problem. Now from my point of view the best advice I can give you is to get a financial C++ books and they will help you hone your talent. What I...
  50. Early Financial C++

    Have you already studied derivatives, VAR or investment theories? If not then you can take these subjects and study carefully. You will encounter a lot of mathematical problems to be built in programming environment. And as for calculus, you can expand your work through many well known...
