PlotFit
PlotFit
is an option to visualization functions such as ListPlot and ListPlot3D that determines how to fit a model to the data.
Details
- PlotFit is used to fit a model to the data, resulting in an approximating curve or surface.
- PlotFitfit determines what method is used to fit a curve to the data.
- Possible settings for fit include:
-
Automatic automatically choose the fitting model 
"Linear" use linear regression 
"Quadratic" use a quadratic model 
"Cubic" use a cubic model 
"Exponential" use an exponential model 
"Log" use a logarithmic model 
"Power" use a power law model 
"Logistic" use a logistic model 
"Local" use LocalModelFit 
"Kernel" use KernelModelFit
