Why do you wanna work at hedge funds as a quant? You might not do more interesting work there, and the pay is highly variable or not better than the Silicon Valley.

Can you arrange the 50 fixed correlations so that the top left corner of the correlation matrix is positive definite? If you can do that, you can apply optimization algorithms such that the top left corner of the matrix is fixed. That should solve your problem.
<t>Let's say we model an OIS short rate process with the Hull-White one-factor model, and there is one OIS short rate process for each currency. From what I gather, usually the correlations between short rate processes are estimated using historical data. The question is what historical data we shou...
QuoteOriginally posted by: katastrofa Mind that you can still keep the real secrets to yourself while talking about / publishing the details of your method if they are in the numerical solutions. Why? Once the details of the method are published, there are no secrets anymore.
<t>QuoteOriginally posted by: CuchulainnAFAIK Matlab is used as a 'second opinion'. Then a black box solution is OK I suppose. They might accept you black box solution.Matlab is used as a language in production in some pension plans AFAIK. Anyway, that's not the point. I can implement the methodolog...
<t>Maybe I over-generalized my statements. Let me put it this way. This is a fundamental technique in probability/statistics, and I have no doubt it can be applied in the mean-variance world. Actually, its applications can be very wide, but let's not go there. Let's say my ultimate goal is to moneti...
I have invented a new methodology that can benefit the buy side (asset management firms, hedge funds, pension plans, insurance companies, etc.) on making portfolio management decisions. Shall I publish the methodology or turn it into a software and sell it?
Given a 6x6 non-PSD correlation matrix, do you want to construct a PSD correlation matrix with a sub-matrix (say, 4x4) fixed? If so, I don't think any methods in the literature help you achieve this.
<t>I have no doubt model validation could be a first step toward model development. However, my question is more concerned about the possible destinations. Depending on what models I validate, the gained experience should be helpful for model development roles at 1. and 2. Are these the only realist...
<r>Can you recommend a few small banks that do interesting model val work? and you are right about my definition of "interesting".QuoteOriginally posted by: ThinkDifferentQuoteOriginally posted by: londonerAccording to this forum, model validation in general is not very interesting and hard to get o...
According to this forum, model validation in general is not very interesting and hard to get out of it. Are there any bright spots in the industry about model validation?Perhaps, someone who have done validation work in more than one bank can share their experience?
Is that a high probability transition from model validation to model development? Obviously, there are more model validators than developers...QuoteOriginally posted by: Marco72Model validation can be a first step towards model development.
