What is another word for curvilinear regression?
Pronunciation: [kˈɜːvɪlˌɪni͡ə ɹɪɡɹˈɛʃən] (IPA) 
Curvilinear regression is a statistical method used to model the relationship between two variables when the relationship is not linear. It is also referred to as nonlinear regression or nonparametric regression. Other synonyms for curvilinear regression include polynomial regression, spline regression, and quadratic regression. These methods allow for a more flexible modeling of the relationship between variables, and can uncover more complex patterns. These approaches are frequently used in fields such as economics, ecology, and social sciences to understand the relationships between variables that cannot be captured by linear models. Despite the different names, all of these methods aim to capture the curvature of the data, and offer alternative ways of modeling these complex relationships.
