Forum,
When regression and ANOVA output report an observed intercept that is
insignificant by the associated p-value, the confidence interval of the slope
includes zero, I ignore the intercept when interpolating or extrapolating. I use the
regression slope in the fitted model w/o the intercept.
Is this acceptable practice?
Thanks for your replies.
