WebApr 26, 2024 · You cannot use fit to solve a problem with errors in both x and y. That does not say the problam is never solvable, but only that fit cannot be used. This is a classic problem, where data has noise in both variables. The curve fitting toolbox only allows for noise in the y variable. So it fits a model that minimizes the residual errors ONLY in y. WebNov 14, 2024 · I am trying to do a fitting of a graph, using the curve fitting Tool and, in particular, using the Weibull option that use the formula: a*b*x^(b-1)*exp(-a*x^b) Despite the fact that the shape of the Weibull distribution seems to be the same of the one of my graph, the height of the Weibull distribution is lower.
