Statistical procedures for variable selection have become integral elements in any analysis. Successful procedures are characterized by high predictive accuracy, yielding interpretable models while retaining computational efficiency. Penalized methods that perform coefficient shrinkage have been shown to be successful in many cases. Models with correlated(More)
BACKGROUND Medicare spending varies substantially across the United States. We evaluated the association between mean regional spending and survival in advanced cancer. METHODS We identified 116 523 subjects with advanced cancer from 2002 to 2007, using Surveillance, Epidemiology and End Results (SEER)-Medicare linked data. Subjects were aged 65 years and(More)
Background This research involves two related areas of examination. The first, " Assessing the Value of New Energy Technologies " focuses on two main tasks. • Developing ways to represent the performance and costs of new energy technologies at representative years in the future probabilistically with and without GCEP support. • Develop a demonstration(More)
CONTEXT Rectus capitis posterior (RCP) muscles have physical attachments to the pain-sensitive spinal dura. Atrophy of these muscles is associated with chronic headache in some patients. The authors suspect that the significance of atrophy in the RCP muscles has been undervalued because the functional role of these muscles is not well defined. OBJECTIVE(More)
A 30 year-old woman who lived in the southern highlands of Tanzania presented with a 5-year history of progressive bilateral foot and ankle swelling. Mossy-like papillomata and block-shaped toes involving both feet were apparent, and the swelling had the consistency of a " water-bag " (Figure 1). The patient denied travel to Tanzania's coastal region. The(More)
BACKGROUND Honey bee (Apis mellifera) drones and workers show differences in morphology, physiology, and behavior. Because the functions of drones are more related to colony reproduction, and those of workers relate to both survival and reproduction, we hypothesize that the microclimate for worker brood is more precisely regulated than that of drone brood.(More)
3 ACKNOWLEDGMENTS I would like to express my sincere gratitude and thanks to my advisor Dr. Robert Moore for his guidance and support throughout my graduate studies. I thank him for giving me an oppurtunity to work with him and for his patience and encouragement throughtout this project. This thesis would not have been possible without his meticulous(More)
