Frequently Asked Questions

When to use nonlinear regression?

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.

What is nonlinear regression vs linear regression?

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.

How is linear regression used in real life?

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.

What is nonlinear regression model?

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.
