WebData fitting Python is a power tool for fitting data to any functional form. You are no longer limited to the simple linear or polynominal functions you could fit in a spreadsheet program. You can also calculate the standard error for any parameter in a functional fit. The basic steps to fitting data are: Import the curve_fit function from scipy. WebJul 21, 2024 · I need help developing a code for a multi-gaussian function. The point would be to create a function that uses the number of gaussian requested by the user to make the final fitting function. All parameters are passed as *params and number of gaussians is deduced from the number of items in *params (1 + n*3).
