nonlinearity: (1) end point straight line fit (see
a least squares best line fit. While a least squares fit gives the
“best case” linearity error (lower numerical value), the
calculations required are burdensome.
(often more desirable in error budget calculations) and the
calculations are more straightforward for the user.
