I want to make kind of a 3d regression and from a set of 3d points (XYZ - Coords) i want to calculate the interpolated plane,that fits best between the set of points.
So far I've only thought of making 3 linear regressions,one on each plane (XY,XZ,YZ) and combining them to create the plane.I don't know if there's an easier,more accurate and better way to do this.
Also what's the precision of the regression equation.it seems like it provides 4 decimals for the a coefficient and 2 for the b constant.Is that good,can i make it provide more accurate equation for the regression it draws?I mean does it use this exact equation or does it display an approximation of the regression it drew?
