通过对直线回归方程进行逆运算，可以进行统计控制，即要求应变量y在一定范围内波动，可以通过控制自变量x的取值来实现。如果某因变量y受多个自变量的影响，如何根据y确定自变量的最佳取值，这是多元回归难以解决的问题，而目标规化方法是解决此类问题的有效途径。方法及原理?
By performing the inverse operation on the linear regression equation, statistical control can be performed. That is, the required variable y fluctuates within a certain range, which can be achieved by controlling the value of the independent variable x. If a dependent variable y is affected by multiple independent variables, how to determine the optimal value of the independent variable based on y is a difficult problem to be solved by multiple regression, and the target planning method is an effective way to solve such problems. Method and principle?
