Estimation of the long-memory parameter from log-periodogram (LP) regression, due to Geweke and Porter-Hudak (GPH), is a simple frequently used method semi-parametric estimation. However, LP estimator suffers finite sample bias that increases with dependency in short-run component spectral density. More recently, Arteche Orbe (2009a, 2009b), context GPH estimator, suggested promising bootstrap ...
We establish a relative spannedness for log canonical pairs, which is generalization of the basepoint-freeness varieties with log-terminal singularities by Andreatta--Wiśniewski. Moreover, we quasi-log pairs.
We give a tropical description of the counting real log curves in toric degenerations varieties. treat case genus zero and all non-superabundant higher-genus situations. The proof relies on deformation theory is version Nishinou–Siebert approach to correspondence theorem for complex curves. In dimension two, we use similar techniques study with Welschinger signs obtain new Mikhalkin’s invariants.
We enumerate and classify all stationary logarithmic configurations of d + 2 d+2 </inline-formu...
Background & Objectives: Peritoneal dialysis is one of the most common types of dialysis in patients with renal failure. However multivariate analysis such as log- rank test and Cox have usually used to evaluate association of risk factors in survival of this group of patients, the aim of this study was to perform of Weibull, Gamma, Lognormal and Logistic Mixture cure models in survival an...
introduction: langerhans cell histiocytosis (lch) is a rare disease characterized by clonal prolifera-tion of histiocytosis in different tissues. permanent consequences (pc) described among subjects with langerhans cell histiocytosis (lch).in this study we report the prevalence of permanent sequel among long – term survivors of lch in our center. methods: we had 30 cases of lch from 1989 – 2001...
Objectives: Identifying the factors influencing the survival of hemodialysis patients using a two- stage survival model and longitudinal multivariate in order to provide the therapist with planning to better control elderly hemodialysis patients. Methods and Materials: The study was a historical cohort study of 395 patients over the age of 60 who underwent hemodialysis. Data were collected ove...
