Is line of best fit slope

WitrynaThe best-fit line through some data is not the same number as the linear coefficient in a polynomial fit. In the example I gave, the best-fit line has a slope that depends on the range of currents you apply, while the linear and quadratic coefficients actually measure separate useful things about the system.
