Missing values are a practical issue in the analysis of longitudinal data. Multiple imputation (MI) is a well-known likelihood-based method that has optimal properties in terms of efficiency and consistency if the imputation model is correctly specified. Doubly robust (DR) weighing-based methods protect against misspecification bias if one of the models, but not necessarily both, for the data o...

impressive. Spain, Italy, France, Germany, and Sweden all lost reigning monarchs, in the days when monarchs really reigned, to the disease. Dr Hopkins has not been satisfied with tracing the European history or even the Western history of the disease; he takes in the Asian dimension, and the African one, and details the effects of smallpox on the ruling houses of China and Japan, and among the ...

We adapt the Douglas-Rachford (DR) splitting method to solve nonconvex feasibility problems by studying this method for a class of nonconvex optimization problem. While the convergence properties of the method for convex problems have been well studied, far less is known in the nonconvex setting. In this paper, for the direct adaptation of the method to minimize the sum of a proper closed funct...

Many have argued that anthropology, as a four-field discipline, lacks intellectual coherence. Recent developments in the field of biotechnology and the possibility of producing chimeras with recognizable human characteristics make it necessary to think in terms of a new kind of “old” four-field holism. The production of a human/nonhuman chimera raises theoretical questions about the nature of t...

I read the commentary1 on ‘Abortion law: campaign groups and the quest for change’ in the October 2006 issue of the Journal with interest. In general, it provides a very balanced overview of the different groups seeking change in UK abortion legislation, summarising the concerns of both pro-life and pro-choice organisations. However, in his discussion and conclusions, Dr Vincent Argent ceases t...

256 20TH ASPEN LUNG CONFERENCE CHEST, 73: 2, FEBRUARY, 1978 SUPPLEMENT Dr. Seceringhau.s: You must know what the HCO is and normalize the data. There really isn’t any difference between the t\V() methods. Proper normalization of the data make the differences go away. In fact, the Pco2 and pH change faster with the steady state method than with the rebreathing method. Dr. Edelinan: Yes, hut one ...

Integration of demand response (DR) programs and battery energy storage system (BESS) in microgrids are beneficial for both microgrid owners and consumers. The intensity of DR programs and BESS size can alter the operation of microgrids. Meanwhile, the optimal size for BESS units is linked with the uncertainties associated with renewable energy sources and load variations. Similarly, the partic...

Deepest regression (DR) is a method for linear regression introduced by Rousseeuw and Hubert [20]. The DR method is defined as the fit with largest regression depth relative to the data. In this paper we show that DR is a robust method, with breakdown value that converges almost surely to 1/3 in any dimension. We construct an approximate algorithm for fast computation of DR in more than two dim...

background: in addition to human leukocyte antigens (hla) compatibility, gene polymorphisms in cytokines might also be important in the quality of allogeneic immune response. objective: to evaluate the influence of hla-dr matching and a number of cytokine gene polymorphisms on acute rejection after living-unrelated donor (lurd) kidney transplantation. methods: a total of 42 renal transplants pe...
