Abstract
This article gives a brief survey of penalized spline smoothing. Penalized spline smoothing is a general nonparametric estimation technique which allows to fit smooth but else unspecified functions to empirical data. We depict the theory behind this estimation technique and we present an example demonstrating how this nonparametric estimation technique can help to gain insight into economics.
