Researchers interested in estimating productivity can choose from an array of methodologies, each with its strengths …, because fundamentally the objective of productivity measurement is to identify output differences that cannot be explained by … technology and erroneous assumptions on the evolution of unobserved productivity. Techniques to control for the endogeneity of …

We consider theoretical bootstrap "coupling" techniques for nonparametric robust smoothers and quantile regression, and verify the bootstrap improvement. To cope with curse of dimensionality, a variant of "coupling" bootstrap techniques are developed for additive models with both symmetric error...

In this paper we present a robust parameter estimation method for jointly estimating shape parameter α, scale parameter γ and location parameter δ of a symmetric stable distribution. The proposed estimation method is based on Probability Integral Transformation (PIT) and robust M-estimators....

The concept of breakdown point was introduced by Hodges (1967) and Hampel (1968, 1971) and still plays an important though at times a controversial role in robust statistics. It has proved most successful in the context of location, scale and regression problems. In this paper we argue that this...
