The choice of bandwidth is crucial in the nonparametric estimation procedure. A number of methods to choose the associated bandwidth have been developed. In this paper we studied three existing bandwidth selectors for local linear regression with different design matrix characteristics. The performances illustrate that although there is no uniformly dominating rule, the variable bandwidth selec...

A data-based local bandwidth selector is proposed for nonparametric regression by local tting of polynomials. The estimator, called the empirical-bias bandwidth selector (EBBS), is rather simple and easily allows multivariate predictor variables and estimation of any order derivative of the regression function. EBBS minimizes an estimate of mean square error consisting of a squared bias term pl...

A bucket selector system has been developed for the KEKB collider. Three VME computers for actual bucketselecting, bunch-current reading and operator interface are working. The system provides a tool for generating the desired filling patterns in the rings.

The International Classification of Diseases 10th version (ICD-10) is one of the standard and most important disease classifications. Since computerized ICD-10 coding systems have drawn a great deal of attention in the medical field, a great number of different coding systems have been proposed. This paper proposes a hybrid architecture of different coding systems. First, given an input disease...
