A study of partial F tests for multiple linear regression models
Get PDFPartial F tests play a central role in model selections in multiple linear regression models. This paper studies the partial F tests from the view point of simultaneous confidence bands. It first shows that there is a simultaneous confidence band associated naturally with a partial F test. This confidence band provides more information than the partial F test and the partial F test can be regarded as a side product of the confidence band. This view point of confidence bands also leads to insights of the major weakness of the partial F tests, that is, a partial F test requires implicitly the linear regression model holds over the entire range of the covariates in concern. Improved tests are proposed and they are induced by simultaneous confidence bands over restricted regions of the covariates. Power comparisons between the partial F tests and the new tests have been carried out to assess when the new tests are more or less powerful than the partial F tests. Computer programmes have been developed for easy implements of these new confidence band based inferential methods. An illustrative example is provided.<br/

Assessing the George W. Bush Presidency: A Tale of Two Terms
Get PDFIn one of the first volumes assessing the full two terms of the George W. Bush presidency, Wroe and Herbert have gathered the work of leading American and European scholars. In fifteen succinct and incisive chapters, authorities such as Jim Pfiffner, John Maltese, Graham Wilson and Alan Gitelson offer assessments of the Bush administration's successes and failures. Extensive attention is paid to Bush's foreign policy, including 'The War on Terror' but the focus is broadened to absorb not only the Bush Doctrine and its repercussions, but also his trade and homeland security policies. The president's domestic leadership in economics and social policy is investigated, as are his dealings as president with the other institutions of the U.S. political system. The result is a comprehensive guide to the Bush presidency and its legacy
Difference based Ridge and Liu type Estimators in Semiparametric Regression Models
Get PDFWe consider a difference based ridge regression estimator and a Liu type estimator of the regression parameters in the partial linear semiparametric regression model, y = Xβ + f + ε. Both estimators are analysed and compared in the sense of mean-squared error. We consider the case of independent errors with equal variance and give conditions under which the proposed estimators are superior to the unbiased difference based estimation technique. We extend the results to account for heteroscedasticity and autocovariance in the error terms. Finally, we illustrate the performance of these estimators with an application to the determinants of electricity consumption in Germany.Difference based estimator; Differencing estimator, Differencing matrix, Liu estimator, Liu type estimator, Multicollinearity, Ridge regression estimator, Semiparametric model
A Subband-Selective Broadband GSC with Cosine-Modulated Blocking Matrix
Get PDFIn this paper, a novel subband-selective generalized sidelobe canceller (GSC) for partially adaptive broadband beamforming is proposed. The columns of the blocking matrix are derived from a prototype vector by cosine-modulation, and the broadside constraint is incorporated by imposing zeros on the prototype vector appropriately. These columns constitute a series of bandpass filters, which select signals with specific angles of arrival and frequencies. This results in highpass-type bandlimited spectra of the blocking matrix outputs, which is further exploited by subbands decomposition and suitably discarding the low-pass subbands prior to running independent unconstrained adaptive filters in each non-redundant subband. By these steps, the computational complexity of a GSC implementation is greatly reduced compared to fully adaptive GSC schemes, while performance is comparable or even enhanced due to subband decorrelation in both spatial and temporal domains
