Here are the objectives to achieve the goal of linear curve fitting −Understanding Relationships: Linear fitting helps to determine how changes in an independent variable (x) affect a dependent variable (y). This understanding can reveal underlying trends and patterns in empirical data which can ...

Curve fitting, on the other hand, is a broader process of constructing a curve, or mathematical function, that best fits a series of data points. For example, linear interpolation can be considered a simple form of curve fitting where the curve is a straight line.Why it is essential?
A log transformation is a relatively common method that allows linear regression to perform curve fitting that would otherwise only be possible in nonlinear regression. For example, the nonlinear function: Y=eB0X1B1X2B2 can be expressed in linear form of: ...
The fitted line plot below illustrates the problem of using a linear relationship to fit a curved relationship. The R-squared is high, but the model is clearly inadequate. You need to do curve fitting! When you have one independent variable, it’s easy to see the curvature using a fitted...

Unfortunately I'm never able to use the Non-Linear Curve Fitting. I'm able to open the dialog, I can choose any function in the dialog, but a fitting never happens. I already tried to fit a diagramm with the formula shown in the dialog, so it must be a "fittable" curve; anyhow ...
