Nonparametric regression - some approaches

In this paper we describe two approaches to nonparametric regression. First, we consider the nearest neighbour approach, as a procedure which serves mainly for obtaining an ad hoc smoothing and interpolating. Next, we describe the roughness penalty approach. This gives a certain compromise between the demand for goodness-of-fit of regression curve to the given data and the condition that the regression curve has not too many oscillations.
