The Gamma Test Data derived estimates of noise for unknown smooth models using near neighbour asymptotics

Abstract

The Gamma test is a simple technique for assessing the extent to which a given set of M data points can be modelled by an unknown smooth non-linear function f . If the underlying model is of the form y = f(x)+r where r is a random variable representing that part of the data which cannot be accounted for by the smooth function f , the Gamma test produces an… (More)
