依据折扣最小二乘法准则,对时间序列建立自回归预测模型,给出了参数的估计公式,数值结果表明该方法更行之有效.
Based on the cut-price least quadratic rule, we establish autoregressive forcast models for time sequence, and propose the formulations of its parameter. The numerical results show that the new method is more efficient than the least quadratic method.
