Labview linear fit error -20002
WebAug 2, 2024 · Where engineers and technicians can get into trouble is by changing the equation order. If a line does not fit well, it may be tempting to try to model it with a parabola, cubic, or another polynomial instead. If they do this, they will get an R^2 value of 1, as they will have found a polynomial that snakes through every data point. Web1 Answer. Sorted by: 7. As a clarification, the variable pcov from scipy.optimize.curve_fit is the estimated covariance of the parameter estimate, that is loosely speaking, given the data and a model, how much information is there in the data to determine the value of a parameter in the given model. So it does not really tell you if the chosen ...
