Estimate Interaction Effects using Eviews 8
Posted: Sun Dec 21, 2014 10:30 am
Hi,
I estimated an equation that includes a dummy variable, GROUP [coded 1, 2, 3] in the following format:
LS VARY C @EXPAND(GROUP)*VARX
Eviews displayed the coefficients for:
C
(GROUP1)*VARX
(GROUP2)*VARX
(GROUP3)*VARX
First question:
I presume the coefficients are the separate slopes for VARX for the 3 groups respectively, am I right?
Second question:
In other statistical software such as Stata the same equation will generate the following results [by default GROUP=1 is the base group]:
C
VARX [ie. the slope of VARX for GROUP=1]
(GROUP2)
(GROUP3)
(GROUP2)*VARX [ie. the difference in slope between VARX for GROUP=2 and VARX for GROUP=1]
(GROUP3)*VARX [ie. the difference in slope between VARX for GROUP=3 and VARX for GROUP=1]
Is there a way to display the above results using Eviews?
Thanks.
Regards,
Ben
