Regression Calculator. Online calculator for curve fitting with least square methode for linear, polynomial, power, gaussian, exponential and fourier curves.

Examples 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.

Curve and Surface Fitting. Curve fitting is one of the most powerful and most widely used analysis tools in Origin. Curve fitting examines the relationship between one or more predictors (independent variables) and a response variable (dependent variable), with the goal of defining a "best fit" model of the relationship.
