Hello! I have some data in which the dependent variable ##y## has, for each data point, an error bar associated with it ##\delta y##. The errors are almost identical for each datapoint, so doing a weighted fit in terms of the errors would not change the results significantly. How can I take the errors into account properly, such that the error bars are reflected in the error on the parameters of the fit? I though initially to have 3 fits for the actual data points, for the upper and for the lower points of the error bars, but I am not sure that would give me what I need, as the function is highly nonlinear and this kind of fit would just influence the overall amplitude, not the other (more important) parameters. Thank you!
