ARMA model estimation

[simonep]

Hello everybody,

I would like to ask you a question about ARMA estimation :

I have to estimate an ARMA model for electricity prices, of the form
φ(B) (P - X) = θ(B) ε
where P is the dependent variable (first difference log price) and X is a set of explanatory variables, defined as:

X = c(0) + c(1)*dummy_1 + c(2)*dummy_2

where the dummies are, for example, 1 on Monday and 0 on other days.

My question is: how can this be done with Eviews? How can I estimate the coefficients c0,c1,c2 AND also the coefficients of the AR,MA terms in the more general model?

Thanks a lot for your kindness
