WebJul 25, 2024 · Low-rank tensor factorization has been widely used for many real world tensor completion problems. While most existing factorization models assume a multilinearity relationship between tensor entries and their corresponding factors, real world tensors tend to have more complex interactions than multilinearity. In many recent … WebThe operation µ also satisfies identities similar to the co-Jacobi and coskew symmetry identities, so while µ is not a cobracket, µ behaves like a Lie cobracket for the Andersen …

However, the sign of investors’ coskew preferences in government bond markets remains ambiguous. In probability theory and statistics, coskewness is a measure of how much three random variables change together. Coskewness is the third standardized cross central moment, related to skewness as covariance is related to variance. In 1976, Krauss and Litzenberger used it to examine risk in stock market … See more For three random variables X, Y and Z, the non-trivial coskewness statistic is defined as: where E[X] is the expected value of X, also known as the mean … See more • Moment (mathematics) • Cokurtosis See more • Harvey, Campbell R.; Akhtar Siddique (2000).
