1. How do select independent variable in modeling?
2. If an independent variable has a negative correlation with the target
variable, why it can get a positive coefficient in the model?
3. Suppose you have a model in a two-dimension space of factors, how do you
design a one-dimension criterion to rank variables?
请教各位，any thoughts for the questions are welcome.
