Inclusion of a second constant term in the mean GARCH equation
Posted: Mon Oct 02, 2017 4:48 pm
Hi all,
I would be very grateful if someone could help me in this issue:
I want to estimate following equation:
ARCH(THRSH=1, fixedlag=32) BOVA = C(1) + C(2)*VARGJR + C(3) + C(4)*VARGJR*BOVA(-1), where:
BOVA is my dependent variable, the returns of the BOVA 11 ETF traded on the Brazilian Stock exchange and VARGJR is the Variance estimated previously using the GJR Model and incorporated in my model.
The problem is the inclusion of the C(3) term. When I include it, the system acuses "near singular matrix"
I attach the eviews file.
Thanks in advance,
Marcelo
