This article considers a linear regression model when a set of exact lin ear restrictions binding the coe cients is available and some observations on the study variable are missing Estimators for the vectors of regression coe cients are presented and their superiority properties with respect to the criteria of the variance covariance matrix and the risk under balanced loss functions are analyzed

The purpose of this study was to assess the reliability of a fi eld and a laboratory test of repeated sprint ability (RSA). Twelve adolescent boys (15.3 ± 0.3 years) completed fi ve trials of both a fi eld RSA test (7 × 30 m sprints) and a laboratory RSA test (7 × 5 s sprints) performed on a nonmotorized treadmill. Mean coeffi cients of variation (CV) calculated across all trials were < 2.7% fo...

Some traditional digital signal processing techniques encompass enhancement, fi ltering, coding, compression, detection and recognition. Recently, it has been presented a new hypothesis of signal processing known as the ability of adaptation of speech signals: an original speech signal may sound similar to a target speech signal if a relocation process of its wavelet coeffi cients is applied. T...

We have considered the estimation of coe cients in a linear regression model when some responses on the study variable are missing and some prior information in the form of lower and upper bounds for the average values of missing responses is available Employing the mixed regression framework we have presented ve estimators for the vector of regression coe cients Their exact as well as asymptot...

The current study evaluated the temporal stability of personality disorders (PD) and traits as assessed by the Schedule for Nonadaptive and Adaptive Personality (SNAP) within a sample being treated for substance dependence in a residential TC. Temporal stability coeffi cients were similar to the few previous studies with clinical samples and comparable retest intervals; however, the current stu...

The Legendre-Stirling numbers are the coeffi cients in the integral Lagrangian symmetric powers of the classical Legendre second-order differential expression. In many ways, these numbers mimic the classical Stirling numbers of the second kind which play a similar role in the integral powers of the classical second-order Laguerre differential expression. In a recent paper, Andrews and Littlejoh...

wileyonlinelibrary.com detectivity of extrinsic photoconductive detectors depends on the ratio of optical carrier generation to thermal carrier generation. Traditionally, extrinsic silicon photodetectors have been limited by either high thermal impurity ionization or low optical carrier generation due to low absorption of sub-band gap radiation. Commonly used group III or V dopants (B, Al, Ga, ...

Modelling of technological processes of heat treatment or welding, involving multiple heat source transitions, requires considering the phenomenon of tempering. In work have been presented results of dilatometric research of hardened C45 steel subjected to tempering. The analysis of the infl uence of heating rate at the kinetic determined from dilatometric curves has been made. There have also ...

We consider posterior inference in wavelet based models for non-parametric regression with unequally spaced data, density estimation and spectral density estimation. The common theme in all three applications is the lack of posterior independence for the wavelet coe cients djk . In contrast, most commonly considered applications of wavelet decompositions in Statistics are based on a setup which...

background: gingival overgrowth is a common side-effect of amlodipine regimen on the oral cavity. there is controversy regarding the cause and effect relationship of periodontal health and drug induced gingival overgrowth. therefore, this study was conducted to investigate and to assess the relationship between the periodontal health and the onset and severity of gingival overgrowth in hyperten...
