در سال های اخیر ترتیب های تصادفی در حوزه های مختلف آمار و احتمال گسترش یافته و احتمال می شوند.دراین تحقیق به بررسی یکی از این ترتیب ها به نام excess wealth می پردازیم. ابتدا تابع excess wealth را معرفی کرده و ارتباط آن با برخی ویژگی های مربوط به توزیع های طول عمر و همچنین کاربرد این تبدیل برای شناسایی داده ها ی دنباله سنگین را بیان می کنیم سپس ترتیب تصادفی excess wealth را معرفی، ارتباط آن با ت...
OBJECTIVE To assess the mortality risks from injuries for smokers and ex-smokers and to quantify the mortality burden of smoking from injury in Taiwan. METHODS Smokers' (and ex-smokers') mortality risks from injuries were compared with that of non-smokers in a merged cohort from Taiwan. A total of 64,319 male subjects were followed up for 12-18 years. Relative risks (RR) (adjusted for age and...
Introduction: Occupational exposure to crystalline silica increases the risk of lung cancer and restrictive lung disease with extensive fibrosis. Silica dust is a major health hazard in foundry factories. The aim of this study was to determine core making workers’ exposure to respirable crystalline silica dust in a foundry factory. Material and Method: This cross-sectional study was conducte...
Excess hazard modelling is one of the main tools in population-based cancer survival research. Indeed, this setting allows for direct due to even absence reliable information on cause death, which common epidemiology studies. We propose a unifying link-based additive framework excess that inclusion many types covariate effects, including spatial and time-dependent using any type smoother, such ...
OBJECTIVE To determine the influence of the total cumulative exposure to excess overall and abdominal adiposity on the incidence of cardiovascular disease (CVD). METHODS Prospective study of 4,061 white and black adults without CVD at baseline in 1985-1986 (age 18-30 years) from the multicenter, community-based CARDIA study. Time-varying excess body mass index (BMI)- and waist circumference (...
In the Canadian National Breast Screening Study, the hazard ratio for breast cancer–specific death was 1.47 for women with cancers detected in the prevalence screening round, 0.9 for women with cancers detected in the subsequent four screening rounds, and 1.05 for women with cancers detected in all screening rounds. Dr. Martin Yaffe claims that these figures are compelling evidence of a randomi...
BACKGROUND Relative survival is commonly used for studying survival of cancer patients as it captures both the direct and indirect contribution of a cancer diagnosis on mortality by comparing the observed survival of the patients to the expected survival in a comparable cancer-free population. However, existing methods do not allow estimation of the impact of isolated conditions (e.g., excess c...
