标 题: 问一道multiple linear regression的题
发信站: BBS 未名空间站 (Wed Nov 30 22:11:20 2011, 美东)
Simple linear regression S1: Y~x(1) (i.e., Y=a1*x(1)+a0); R2 (coefficient of
determination) = 0.01 ;
Simple linear regression S2: Y~x(2) (i.e., Y=b1*x(2)+b0); R2 (coefficient of
determination) = 0.02 ;
Then multiple regression M3:Y~x(1) and x(2)(i.e., Y=c2*x(2)+c1*x(1)+c0); wha
t is the min and max of the R2 for this regression?
thanks!
