The Score of Conditionally Heteroskedastic Dynamic Regression Models with Student T Innovations, and an Lm Test for Multivariate Normality

Sentana, Enrique; Fiorentini, Gabriele; Calzolari, Giorgio - 2001

We provide numerically reliable analytical expressions for the score of conditionally heteroskedastic dynamic regression models when the conditional distribution is multivariate t. We also derive one-sided and two-sided LM tests for multivariate normality versus multivariate t based on the first...
