Nonlinear regression

Nonlinear regression is a type of regression analysis in which data follows a model and is then represented as a function of mathematics. Simple linear regression relates to two variables (X and Y) with a straight line function, , whereas nonlinear regression has to generate a curve. Nonlinear regression uses a regression equation, which is as follows:

Let's look at this formula:

• X = A vector of p predictors
• β = A vector of k parameters
• f(-) = A known regression function
• ε = An error term

Nonlinear regression can fit an ...
