Description: 907求多元线形回归方程及预报
一．功能 x1，x2, x3,………..xp为自变量，Y为随机变量，
求线形回归方程
Y= + +…+ +
其中 。。。， 为常数， 是随机变量，且 —N（0， ）
来描述Y与X的变化规律。并用T检验法检验线形回归是否显著。
如果线性回归显著，可用经验回归平面方程对Y作出预报，并给出预报值的置信区间。
-907 for multiple linear regression equation and a prediction. Functional x1, x2, x3, ... .. xp as variables, Y random variables, linear regression equation for Y = ... which. . . For the constant, random variables and-N (0), to describe the X and Y changes. Using T-test whether linear regression significantly. If the linear regression notable experience available on the return plane equation Y forecasts, and gives the predicted confidence interval. Platform: |
