Adaptive weighting for flexible estimation in nonparametric regression models.

Nosedal-Sanchez, Alvaro - 2011

We propose a new method to find spatially adaptive smoothing splines. This new method breaks down the interval [0, 1] into p disjoint sub-intervals. Then we define p functional components in [0, 1], which have two importantfeatures. First, the purpose of each of these p components is to estimate...

Testing forward exchange rate unbiasedness efficiently: A semiparametric approach

Hodgson, Douglas J.; Linton, Oliver; Vorkink, Keith - 2004

We apply semiparametric efficient estimation procedures for a seemingly unrelated regression model where the multivariate error density is elliptically symmetric to study the efficiency of the foreign exchange market. We consider both cointegrating regressions and standard stationary...

Sample size determination for kernel regression estimation using sequential fixed-width confidence bands

Dharmasena, L. Sandamali; Zeephongsekul, P.; de Silva, … - 2008

We consider a random design model based on independent and identically distributed pairs of observations (Xi, Yi), where the regression function m(x) is given by m(x) = E(Yi|Xi = x) with one independent variable. In a nonparametric setting the aim is to produce a reasonable approximation to the...

Nonparametric estimation of first passage time distributions in flowgraph models

Collins, David - 2009

Statistical flowgraphs represent multistate semi-Markov processes using integral transforms of transition time distributions between adjacent states; these are combinedalgebraically and inverted to derive parametric estimates for first passage time distributions between nonadjacent states. This...

Innovation in Business Groups

Belenzon, Sharon - 2010

Using novel data on European firms, this paper investigates the relationship between business groups and innovation. Controlling for various firm characteristics, we find that group affiliates are more innovative than standalones. We examine several hypotheses to explain this finding, focusing...
