| 摘 要： | 为了使回归预测模型更具有实用性，采用渐近最小二乘法对指数函数，幂函数一类回归曲线的参数估计做了改进。在增加新的样本单元资料时，用增长记忆递推公式对原始回归预测模型进行了校正，得到新的预测模型。

| Abstract: | In order to make regression forecasting model be more useful, this paper improved the parameter estimation of regression curves of exponential functions and power functions by using the improved asymptotic least square method. The original regression forecasting model was rectified by using recursion formula of increasing memory. When the sample units increased, a new forecasting model was got. |
