I'm planning to build a PC for running heavy simulations that would take up days, probably even weeks on my current workstation. Let's say I want to build a computer solely for simulation purposes. Is CPU then the only component that matters? Or does RAM play a part too?

How do I generate n random variables, \(X_i\in\{-1,1\}\) with known probabilities \(p_i=P(X_i=1)\) and \(p_{ij}=P(X_i=1 \wedge X_j=1)+P(X_i=-1 \wedge X_j=-1)\)? 
 I found a package for R for simulating binary variables (i.e. \(X_i\in\{0,1\}\)), however, it doesn't produce the correct result if I...

Let's say that you are certain that the price of a stock is going up in the near future. You don't know how much it will go up, only that it most certainly is not going to decline. Of course, this is not necessarily a realistic situation, but let's say you are 100% sure that the stock won't...

I'm about to start PhD studies. However, I have a tough decision between two departments: Finance and Quantitative Economics. I need to decide which one to choose and it will be a major decision since I will be affiliated with that department for the next 4-5 years. Here are the pros and cons...

I have been interviewed for a financial analyst's position in a large commercial bank. I'm not particularly keen on the position, I'm more or less trying to find out what I want to do. To me, a (qualitative) analysts job has always seemed like bogus, sort of like fortune telling. To my...

I am currently using statistical programming languages, such as R, for optimization processes. The problem is, R and the like can be deadly slow when it comes to for-loops and iterative processes. Is C++ the best language when it comes to speed and performing loops? In general, what is the best...

I'm a graduate student in Finance, currently doing research for my Master's thesis. My studies have been going quite well and I have a lot of interest and knowledge on mathematical finance and investment management, so I have started to think about doctoral studies. I have a background in...
