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:
  • Automaticautomatically choose the fitting model
    "Linear"use linear regression
    "Quadratic"use a quadratic model
    "Cubic"use a cubic model
    "Exponential"use an exponential model
    "Local"use LocalModelFit
    "Kernel"use KernelModelFit
    modeluse the provided FittedModel

Examples
