| 鐵路保價收入趨勢變化分析與預(yù)測模型的建立(30 卷) |
| 英文標題 |
| Analysis on Trend Change of Railway Value-insured Revenue and Establishment of Forecast Mode |
| 摘要 |
| 為做好鐵路保價收入預(yù)測，運用散點圖、分層圖、方差分析等方法對樣本數(shù)列的變化趨勢進行分析；建立了三角函數(shù)直線趨勢季節(jié)預(yù)測模型，運用最小二乘法通過建立正規(guī)方程進行參數(shù)估計。通過對2008年的保價收入進行預(yù)測及分析，提出利用擴展富里哀項減小預(yù)測偏差的方法。 |
