Hello,
I am new to Eview(7), though I have been going throught the manual.
I am trying to run a one-step regression for an Event Study using dummy variables in order to capture Abnormal Returns *(ARs) during Event Period. My model is the in the form:
Rft - rf = αi + βi (Rmt - rft ) + ∑_(τ=1)^T γiτ Di,τ,t + εit
Where γ which is the coefficent of the dummy variable measures the ARs.
I have the other variables ready, how do I set the Dummy to be equal to 1 during the Event Period and 0 otherwise, when inputting into the Eviews.
Thank You.

Re: Estimating Abnormal Returns with Dummy Variables
First step, set all the values of the dummy equal to zero.
Second step two ways:
a) Double click on the series DUMMY and edit it by typing in 1's during the event window.
or
b) Set the sample to the event window and set DUMMY=1
Code: Select all
series dummy = 0a) Double click on the series DUMMY and edit it by typing in 1's during the event window.
or
b) Set the sample to the event window and set DUMMY=1
Code: Select all
smpl first_date_in_window last_date_in_window
dummy = 1
