Hello,

I am hoping someone can help me with a few regression questions. I am running a number of simple linear regressions....Do I want to (should I) include a constant in the equation?

Also, when I do run the regressions with the constant my r2 values are all very low (0.00006 - 0.05)...I realize that only really tells me about what amount of variability can be predicted by the independent variable, but when they are that low are is the ability to predict important at all (even when they are significant at p<0.01)???

Need some help...Thanks
