bivariate GARCH with variance regressor

[dakini]

hi:

i am struggling with bivariate GARCH estimation and really NEED help please!!

i use eviews 6 which works very well as estimating multivariate GARCH in a system, but when i add one or two variables as variance regressors, no std error and p value are reported, I am very confused about the results, can anybody tell me where the problem is?

appreciate very much!!
