Thank you for your reply - it is actually quite simple. I didn't think to look at duration as an expectation.

I know that duration decreases as spot rates increase. This is evident from taking the partial derivative of duration w.r.t to the yield. But how can that relationship be expressed in the form of Jensen's inequality: (E[X^{2}] \leq E[X]^{2}) Any help will be appreciated!!!

An excellent explanation, Quantyst. This problem is akin to the classic example of defective antennas. Anyways, here is another fairly simple one I came across in a teaser book the other day. This one also involves an application of the counting principle: A parking lot contains 100 cars...

A candy factory has an endless supply of red, orange, yellow, green, blue, and violet jelly beans. The factory packages the jelly beans into jars of 100 jelly beans each. One possible color distribution, for example, is a jar of 58 red, 22 yellow, and 20 green jelly beans. As a marketing...

I've been alternating between that and the breakpoint, but I was hoping for a setting/option that would take care of it. If not, then I'll just probably just go with the 'cin >> variable;' method. Thanks anyway.

Hey guys Have somewhat of a silly question about Visual C++ 2008...whenever I compile and run a program, the output window just pops up and closes right away. I can get around it by creating a breakpoint at the last line in my code, but having to do that every time is somewhat of a pain in the...

Minh Tran & Bigbadwolf, Thank you for you replies - I went back and looked at the areas I hard trouble with and turns its the axiomatic treatment of probability. I'm fine with the calculus and finance aspects of it but its the probability thats giving me a bit of trouble. Are there any books...

Hey guys, I picked up Shreve Vol. 2 a couple weeks back. I was wondering, is it ok if I don't pick up on some of the concepts right away? Some of the concepts are quite straightforward, but sometimes when he goes in the little nuances and technicalites I tend to get a bit lost. Is this...

Duh! I feel dumb. I overlooked the fact that the solution is uniquely determined in (xy) plane only where (x^{2}\leq y^{2}) Thank you

I'm trying to teach myself PDEs over the summer, so I can take more advanced math classes in the fall. I just started a few days ago, and I'm stuck on a problem. I'm sure the problem probably seems easy, but I can't seem to solve it properly. (y*u_{x} + x*u_{y} = 0) (U(0,y) = e^{-{y^{2}}}) I...

I don't know much about technical analysis but I often hear the following two terms: fast stochastic oscillator and slow stochastic oscillator. As to their meanings, I have no clue and nor do I care. But for your question, you might want to look into it.

By reputable, I mean something along the lines of top 10 in physics. MIT, Stanford, Harvard, Cal-Tech, Princeton, Michigan, Johns Hopkins, UCB and so on. As opposed to University of Phoenix... :D

I looked at the admissions requirements of some of schools - it's I'd have to take some time to complete an undergrad physics degree first.

But is it possible to get into a Physics or another hard science PhD at a reputable school after completing a Masters in Fin. Math - especially considering my undergrad majors were Finance & Econ?

Seanny, There are several schools who now offer PhDs in Fin Math...FSU, BU, CMU, UF, and Claremont offer doctorates in Fin. Math specifically. But after reading Dominic's post, I did a bit of digging and realized there is little, if any, difference between a Fin Math Phd and a Finance Phd.

For a few reasons.. 1) it's a personal goal 2) if for some reason, after working as quant, I decide it is not for me, having the phd would allow me to, perhaps, have academia as a backup 3) 30-40 years down the road, I'd like to settle into academia

Greetings everyone, First off, I have to say that Quantnet is brilliant! So much information and so many people willing to help! I'd like to hear some of your opinions on which degree would be more useful for a job in FE: PhD Finance or Phd Financial Mathematics? I plan on attending an FE...
