摘要：The Report projects quarterly production and stock levels for the Minnesota and U.S. iron mining industry to the year 2000. Projections of Minnesota's iron industry employment are subsequently derived from the production forecasts. Ordinary least squares regression techniques are used to analyze the seasonality patterns that existed between 1955 and 1978. The regression equations, based on the quarterly data, were calibrated so they could be used to seasonalize the annual iron ore consumption, production and import projections developed by the U.S. Bureau of Mines. Alternate industry forecast series are presented to facilitate comparison with the yearly baseline projection series.
