3d plot of regression squared error
Hi. I'm trying to create a 3d plot for a teaching example of finding a
least-squares estimate of the parameters to fit a line to some data. I
was hoping to get a nice plot with a clear, single minima where the
derivative of the surface is zero. No matter how much I tinker, I can't
seem to get a simple straightforward plot. Am I doing something wrong?
Thanks in anticipation,
Ross-c
