So, the intercept is usually described as a single volume of X1, X2 = mean, and X3 = suggest. And I am able to see that there is a three-way conversation through which for a person degree of X1 (relative to your intercept as described earlier mentioned), as X2 goes up and X3 goes up by one unit, I need to regulate the estimate for The easy impact of that standard of X1 by some total.
