### 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.)
