Nonlinear regression is used for two purposes Scientists use nonlinear regression with one of two distinct goals: **•To fit a model to your data** in order to obtain best-fit values of the parameters, or to compare the fits of alternative models.

Typically, in nonlinear regression, you don't see p-values for predictors like you do in linear regression. **Linear regression** can use a consistent test for each term/parameter estimate in the model because there is only a single general form of a linear model (as I show in this post). In that form, zero for a term always indicates no effect.

**Linear** **Regression** is a basic statistical analysis of predicting the outcome of a continuous variable. The idea is to draw a relationship between the dependent and independent variables. Based on a set of predictors, we try to predict the outcome of a continuous variable. **Linear** **Regression** is **used** in a lot of areas in **real** **life**.

In statistics, **nonlinear** **regression** is a form of **regression** analysis in which observational data are **modeled** by a function which is a **nonlinear** combination of the **model** parameters and depends on one or more independent variables. The data are fitted by a method of successive approximations.
