Hi Rers,
I have a poission time series model with 5 parameters. I just wanted to
remove two of the lag on response in the model and put it as a system model.
I am not sure about the codes to combine these two on R. If anybody has any R
example (code), please post it.
My original model:
log(Y(t))~constant+b1*Y(t-1)+b2*Y(t-2)+b3*(variable1)+b4*(variable2)+e
I would like to construct a model:
log(Y(t))~constant+b1*(variable1)+b2*(variable2)+X(t)
X(t)~phi1*Xt-1+phi2*Xt-2+error
where X(t) is the autoregressive lag effect of response.
A.K.
