Analysis of crosscorrelations between financial markets after the 2008 crisis
(Elsevier BV, 2013)We analyze the crosscorrelation matrix C of the index returns of the main financial markets after the 2008 crisis using methods of random matrix theory. We test the eigenvalues of C for universal properties of random ... 
An inequality on guessing and its application to sequential decoding
(Institute of Electrical and Electronics Engineers, 199601)Let (X,Y) be a pair of discrete random variables with X taking one of M possible values, Suppose the value of X is to be determined, given the value of Y, by asking questions of the form "Is X equal to x?" until the answer ... 
An inequality on guessing and its application to sequential decoding
(IEEE, Piscataway, NJ, United States, 1995)Let (X,Y) be a pair of discrete random variables with X taking values from a finite set. Suppose the value of X is to be determined, given the value of Y, by asking questions of the form 'is X equal to x?' until the answer ... 
Joint mixability of some integer matrices
(Elsevier B.V.Elsevier BV, 2016)We study the problem of permuting each column of a given matrix to achieve minimum maximal row sum or maximum minimal row sum, a problem of interest in probability theory and quantitative finance where quantiles of a random ... 
On the Hajek projection for truncated and censored data
(Scientific Publishers, 1993)Large sample properties of the productlimit estimators for truncated or censored data are usually achieved via the empirical cumulative hazard function estimators. Hajek projection of the empirical cumulative hazard ...
