I have managed arrive a solution and programmed it in VBA for three quadratic equations and three unknown. However, I seem to be getting lost in weeds trying to write a general solution for a,b,c,d in the following:
Points: (Y1,X1), (Y2,X2), (Y3,X3), (Y4,X4)
Points: (10,2), (5,4), (4,11), (4,15)
Four Equations with 4 variables:
a) Y1=a+bX1+cX12+dX13
b) Y2=a+bX2+cX22+dX23
c) Y3=a+bX3+cX32+dX33
d) Y4=a+bX4+cX42+dX43
I am searching for the solution and was hoping someone had already done this.
