forecast result is NA

Postby amberosw » Wed Apr 06, 2011 1:18 am

Hi I have an estimation equation AR(1) AR(7) and some dummy variables for day of the week, and an exogenous variable for temperature (lag 1). When I try to use the equation to forecast, the result of the forecast is NA. Could you help me with this? Thank you.

btw, I'm only trying to forecast 1 step ahead. Both dynamic and static forecast gives me the NA result :(

Probably your exogenous variable does not have any observations for the forecasting period.
