运用逐步回归和主成分分析的方法，选取了装甲车辆诸多战技性能指标集合中的自变量子集，建立了该子集与使用与保障费用之间指数回归方程组。该模型也可推广应用于装甲车辆综合性能的评估。
The method of stepwise regression and principal component analysis is used to select the subset of independent variables in many combat technology performance indexes of armored vehicles. The exponential regression equations between the subset and the usage and support costs are established. The model can also be extended to evaluate the comprehensive performance of armored vehicles.
