Monthly vs Annual Data
Posted: Tue Jun 18, 2013 5:56 am
I have log data on monthly time series of average gross wages, for Jan 2002 till Aug 2008. I need to figure out the correct ARIMA(p,d,q) model for the annual growth rate of wages. Is there something I need to do, for example a data transformation, before I perform Box-Jenkins modeling?
Thanks!
Thanks!
