A robust approach to joint modeling of mean and covariance structure using the multivariate t distribution

碩士 === 中興大學 === 應用數學系所 === 95 === This thesis extends the previous work of Pourahmadi(1999, 2000) by introducing a robust version of joint mean-covariance modeling approach based on the multivariate t distribution. The modified Cholesky decomposition is adopted to factorize the variance component in...
