摘要
通过对历年数据的分析,运用逐步回归法确定影响专业人才数量最显著的因素,得出影响专业人才数量的最佳多元回归模型,并对回归方程和各个因素进行显著性检验,给出预测结果的置信区间.
By analysing the historical data with stepwise regressive method, the most significant factors affecting the quantity of specialized brains are worked out, and the optimized multivariate linear regressive model and each significant factor are determined. Finally, the confidence interval of the prediction is presented.
