discriminatory analysis for forecast
判别分析预测法(diseriminatory analysisfor foreeast)又叫分辨分析法，是用判别函数预测害虫发生量的方法。其步骤为:将预报因子和预报量分为2级或多级，对预报因子进行线性组合，构成一个判别函数;先确定一个临界值作分辨指标，然后计算判别函数式中的系数，求出临界值;应用时，将预报因子的实查值代入判别函数式，求出预报值，将此值与临界值相比较，可预报害虫的发生量。 判别函数通式将预报因子的数据进行线性组合: 尸y~习c、·x、(1) 左=l式中夕为预报量;P为预报因子个数;x、(k二1，2，……，尸)为预报因子;c、为系数。二级判别法中的x分为2级，故(l)式为:〕一clxl+cZxZ(2)则y值亦分2级，可确定一个y。为分辨指标，当夕)yc时为A级，夕
