摘要

We provide our main motivation for introducing covariance regression modelsCovariance regression model. Then, we present covariance regression models and study theoretical properties of regression parameter estimators. We subsequently analyze non-Gaussian covariance regressionNon-Gaussian covariance regression models and explore the covariance model with general linear structureGeneral linear structure. Finally, three empirical examples are briefly discussed.
