How to interpret b0 in regression
WebHowever, this is only a meaningful interpretation if it is reasonable that both X1 and X2 can be 0, and if the dataset actually included values for X1 and X2 that were near 0. If neither of these conditions are true, then B0 really has no meaningful interpretation. It just anchors the regression line in the right place. http://www.bwgriffin.com/gsu/courses/edur8132/notes/Notes8c2_RegressionCoefficientsInterpretation.pdf#:~:text=Interpretation%20of%20Regression%20Coefficients%201.%20Simple%20Regression%20with,Y%20for%20a%20one%20unit%20increase%20in%20X
