WebContext¶. Creating well scaled models is important for increasing the efficiency and reliability of solvers.

"WebNov 16, 2024 · The lesson here is that the marginal effect depends on scale because a marginal effect is a derivative, which is a slope. Remember, in the easiest case of a straight line, the slope is the change in y for a one-unit change in x. If you change the scale of x (by multiplying or dividing it by a number), the slope will change accordingly. " - Poorly scaled
