The following paper describes the results of the forecast activity applied on steel prices time series, the method used in this analysis is a rolling window ARIMA regression. The forecast activity is built on prices time series that have been collected by anonymous weekly surveys sent to a sample of steel Italian operators. This pricing collection activity officially started in 2012 thanks to a tight cooperation between DMS stat Lab and Siderweb.
