WebExamples of the uses of the fit functions. You need to input rough guesses for the fit parameters. Sometimes just guessing "1" for each parameter will work. For fitting functions with a "c" parameter, you can choose to fix the value. This option allows you to use "c" as a parameter without varying the value during least squares adjustment. WebJul 29, 2024 · If I have a set of data that ( x i, y i) could be visualized on a scatter plot, and I want to apply the least-square method to fit them using a Gaussian function: G ( x) = B + A exp [ − ( x − μ σ) 2] I think this would give us an estimation of the expected value μ.
