I am talking to a group, which is practicing "Quantitative Arbitrage". This seems to be different than the statistical arbitrage mentioned serveral times on this forum earlier. Can any wise man here share some insights, experience or speculation?Thanks for your input.

<t>How about this? ifstream fin("data.txt"); int temp[3]; char tmpch; while (fin >> temp[0] >> tmpch>> temp[1] >> tmpch>> temp[2]) { cout << temp[0] << ',' << temp[1] << ',' << temp[2] << endl; fin.clear(); fin.ignore(std::numeric_limits<std::streamsize>::max(), '\n'); } fin.close(); Of course, this...

<t>With the least function calls, you should do this:using namespace std;vector<int> test3(test1.size()+test2.size());merge(test1.begin(), test1.end(), test2.begin(), test2.end(), test3.begin());// As the test1 and test2 are already sorted, so test3 is also sorted by "<".vector<int>::iterator end = ...

The website is built with MS Frontpage's scheme with modification by hands, and I guess that I am not alone in the bad taste. Thanks for the suggestion. I'll try to change it.

Sorry. Double replies.

QuoteOriginally posted by: CarolynTA better chance to market yourself is to post most of solutions to exercises in Duffie's DAPT book on your web.Sorry. I haven't read this book yet. Now, it is on the top of my book list. I will do it as soon as I start it.Thanks for the advice.

<t>A friend of mine recommended the quant group in PPL (Pennsylvania Power & Light) to me. I cannot find enough information about them on the internet. Does anyone here have more information on them? What they do? And what kind of stuff that they are mainly dealing with?Thanks in advance for any...

<t>I am going to get my Ph.D. in Physics this December, and am searching for an intern or entry level opportunity anywhere in US. I just want to get the opportunity to gain some real world experience in quantitative finance. I wouldn't mind to just work for experience without monetary compensation f...

<t>Please see the warning at the end!!!!!Sorry. I cannot reproduce your error in the following versions of Mathematica: 4.0 Linux, 4.2.0 Linux, 4.2.1 Linux, and 5.0.0 Win32.The error message you get is due to the failure of NonlinearRegress. I accidentally found out this when I failed to define VolD...

Try to do Needs["Statistics`NonlinearFit`"]before you run the NonlinearRegress. Just like NonlinearFit, NonelinearRegress also needs Statistics`NonlinearFit`.If this doesn't solve your problem, check the version of your Mathematica. It works in Mathemtica 4.2.1.0.

Did you tried the NonlinearRegress method? It did exactly what you wanted.Here is the result:{a -> 1.197071784342699`, b -> -1.606134993286988`, c -> 3.2666722896250926`, d -> 0.0008110958925133949`}

<r>Why don't you use NonlinearRegress? It is much easier. Try the following:BestFitParameters /. NonlinearRegress[data, 1/(4*c^3)*(b^2 + 2*a*b*c + 2*(a^2)*(c^2) + 8*b*c*d + 8*a*(c^2)*d + 4*(c^3)*(d^2)*t) - Exp[-c*t]*(8*b*c*d + 8*a*(c^2)*d + 8*b*(c^2)*d*t) - Exp[-2*c*t]*((b^2) + 2*a*b*c + 2*(a^2)*(c^...

Now I know what it is, and I should find more information about it. Thanks.
