I have three vectors X1, X2, Y and want to find out the possible dependence
of Y on X1 and X2.
Logistic Regression is adopted.
However, I got confused because of the following results:
If I fit the Logitstic Regression model for X1 and Y, or for X2 and Y, the
results show that X1 and Y are clearly correlated, so are X2 and Y.
fitting model: OddRatio(Y)=a+b1*X1 |
