Regression equation for January effect

[nong_cnt]

Hi All,

I am new to Eviews. I'm sorry if I ask a dumb question.
I need to test january effect on the stock market. I have a monthly return data.

My model to test January effect:
Return = B1D1 + B2D2 ... B12D12

D1-D12 are dumy variables representing january to december.
B1-B12 are representing the estimate of a mean return from Jan to December.

The problem is how do I put this into e-view and get the result.

Thanks,
Narongsak
