They place restrictions on how the inputs can influence the response, for example forcing the relationship to act through a linear model. This is called parametric analysis because these models have parameters and you fit a model to the data by optimizing parameters.

Nonparametric regression algorithms make fewer assumptions about the relationship between x and y. In their purest form, these algorithms will learn the true relationship between x and y as you observe more data, regardless of what this truth looks like. As you accumulate data, your predictions ...
