近年来,计算机在农业上已得到广泛的应用,如预报产量、分型划类、寻找最佳生产方案、确定作物生产的主导因素等等,都已开始在计算机上进行。在计算机上定量预报,离不开数学模型。本文试就相关(回归)分析这一数学方法和模型,在计算机上进行农作物产量预报问题,浅谈管见。众所周知,农作物产量的形成,是由许多因素决定的。可以认为,产量是许多参数 X_1、X_2.X_3……X_n
In recent years, computers have been widely used in agriculture, such as forecasting yield, classification and classification, finding the best production plan, determining the dominant factor of crop production, etc., have all started to be conducted on the computer. Quantitative prediction in the computer, can not do without the mathematical model. This paper tries to analyze (mathematically) this mathematical method and model based on correlation (regression), forecast the yield of crops on the computer, talk about management. As we all know, the formation of crop yields is determined by many factors. It can be considered that the yield is a number of parameters X_1, X_2.X_3 ... X_n
