The error might be generated by one of the following:1) you need to look at the underlying deposit Start/End dates, not the futures expiry. So for example Eurodollar futures are linked to a 3M libor deposit s...

Cholesky Decomposition: Covariance or Correlation Matrix?

<t>Isn't it just a scaling issue?you start by N(0,1) (Multivariate Normal)to get to N(0,Sigma) (Sigma being covariance matrix) you use choleski since N(0,Sigma) = Sigma^(1/2) N(0,1) in distributionSigma^(1/2) is your choleski decomposition of the covariance matrix. (any other decomposition will do a...

stock options and corporate actions

<t>Hi,it really depends on the terms of the deal and on the exchange, as they have different rules. Check out a few websites like Euronext , Eurex, IDEM, MEFF, CBOT etc. You can go trough the rules and then trough some examples in the official press releases (Pretty much every exchange has a corpora...

Banks are paying 90-100k basic +30-40k guaranteed to Masters/Mba fresh out of school without a significant experience. and to be honest, I can't really see any real difference between a top undergraduate from continental Europe and the average breed coming ...

Orthogonal Regression

<t>I think Learner means something different.OLS you basically project your dependent variable on the linear space spanned by the independent ones.With the orthogonal regression, you look for the hyperplane that explain the maximum variance of both dependent and indepentent variables.
