nonparametric model

(model developed avoiding assumptions regarding a basic structure)

A nonparametric model is a model that does not begin with a particular relation assumed, e.g., a linear, square, or exponential relationship or a common statistical distribution. The name can mislead because the model relationship ultimately will have parameters, often many, but not just a few pre-specified parameters to discover and plug into a particular formula. The result may be a sizable polynomial in a form such that many different function "shapes" can be approximated. (Though my description is in the manner of one independent variable and one dependent variable, that is just a simple case.)
