摘要
统计预报中常用的多元回归模型,由于预报因子的非线性及模型数据的非正态性等情况,影响预报效果,针对这些问题,本文提出非线性稳健回归模型,使预报的准确率得到提高。
The multivariate regression model is often used in the statistical forecasts. But the forecast accuracy is influenced by both non-linearity of predictors and the non-normality of the date. The model of nonlinear robust regression is introduced in this paper, in order to improve the forecast accuracy greatly.
