On HNBUE class after specific age
athemat s.2012.1 Abstract In this article we introduce new classes of life distributions namely harmonic new better (worse) than used in expectation after specific age t0 HNBUE t0 (HNWUE t0). The closure properties under various reliability operations such as convolution, mixture, mixing and the homogeneous Poisson shock model of these classes are studied. Furthermore, nonparametric test is pro...
متن کاملCharacterizations of exponentiality within the HNBUE class and related tests
A harmonic new better than used in expectation (HNBUE) variable is a random variable which is dominated by an exponential distribution in the convex stochastic order. We use a recently obtained condition on stochastic equality under convex domination to derive characterizations of the exponential distribution and bounds for HNBUE variables based on the mean values of the order statistics of the...
متن کاملAge Specific Reference Levels of Serum Prostate-Specific Antigen, Prostate Volume and Prostate Specific Antigen Density in Healthy Iranian Men
Background: It is relevant to highlight that there is not a precise and perfect report on either 95 percentile value (upper limit of normal range) or on appropriate reference intervals for serum PSA in Iranian population. Objective: To determine age-specific reference ranges for serum prostate-specific antigen (PSA) concentration and PSA density (PSAD) and prostate volumes in a population of he...
متن کاملThe Effectiveness of Assertiveness Training on Anxiety Symptoms in School-Age Children With Specific Learning Disorder
Objective: Specific learning disorder is a type of neurodevelopmental disorder, in which children with disabilities have difficulty understanding, or using spoken and written language. The disorder diagnoses when children have significant reading, writing, and math skills lower than expected. One of the characteristics of children with a learning disorder is the presence of anxiety symptoms, wh...
متن کاملTempo effect on age-specific death rates
It is widely known that shifts of cohort fertility schedule can produce misleading trends in period TFR. This note shows that such a “tempo bias” can occur in age-specific mortality as well: if the age distribution of cohort deaths shifts toward older (younger) ages, the period age-specific death rate is biased downward (upward). 1 Laboratory of Populations, Rockefeller University, 1230 York Av...
