The value of the intercept, a, anchors the scatterplotâs regression line relative to the values of X and Y (and their coordinates) for the problem at hand. Oftentimes the intercept is a mathematical abstraction but it serves a function of adjusting predicted values of Y relative to the plot.
In this case, the intercept is the mean of the reference group, and each of the unstandardized regression coefficients is the difference in the dependent variable between one of the treatment groups and the mean of the reference group (or control group).
