摘要
以某港口1996—2002年吞吐量为原始数据,按照“误差平方和最小”的准则,把一元线性回归模型和GM(1,1)模型组合起来,对某港口2004—2008年的吞吐量进行了组合预测。
Taking the port throughput of a port from 1996 to 2002 as the original data and adopting 'the minimum value of the sum of error square' as the optimal rule, a combined forecasting model was established by combining unitary regression model and GM (1,1) model to forecast the port throughput of a port from 2004 to 2008.
