I would like to find the best fit of two variables for a number of approximate equations, such as:
1x+2y+2=7.04 2x+y+4=7.98 1.5x+1.5y-2=2.53 1.8x+3y-1=6.77
That should come up with a result:
x = ~1,
y = ~2 (exact value for whatever the best fit is).
I can't find any inspiration in either
I don't expect anyone to do it for me, but perhaps someone could push me in a correct direction?
Thanks in advance, r.
