and span a plane, and lives off it. Drag the scene to look around, then click project and watch appear as the shadow of on the plane, with left over and perpendicular to it. The two sliders control one thing, how correlated the regressors are, and that one thing drives both of the problems below.
this is the true 3D angle, and moving the camera never changes it. Two correlated vectors can look perpendicular from the right viewpoint, so trust this number, or below, and not your eyes.
this sets the quality of the fit, since . At 1° the fit is almost perfect, at 85° there is almost none. It moves only perpendicular to the plane, so stays where it is.
this one is only for viewing. , and all scale together, so θ, R², corr and VIF do not move. Turn it down whenever the other sliders push out of view.
