In this paper, we consider the estimation of the unknown parameter of the scaled logistic distribution on the basis of record values. The maximum likelihood method does not provide an explicit estimator for the scale parameter. In this article, we present a simple method of deriving an explicit estimator by approximating the likelihood function. Bayes estimator is obtained using importance samp...

The goal of the study was to assess the quality of life (QOL) and depression and provide further insights into the relationship between QOL and depression among community-dwelling elderly Chinese people. Baseline data were collected from 1168 older adults (aged ≥ 60) in a large, prospective cohort study on measurement and evaluation of health-promoting and health-protecting behaviors interventi...

Scale-free graphs have recently attracted much attention since so-called scale-free phenomena have really appeared in various physical and social networks, where a graph is said to be scale-free if the distribution of degrees has a power-law tail. In the previous paper, the authors proposed a simple model of random interval graphs generated by immigration-death processes (also known as M/G/∞ qu...

OBJECTIVE To examine the use of the term 'metric' in health and social sciences' literature, focusing on the interval scale implication of the term in Modern Test Theory (MTT). MATERIALS AND METHODS A systematic search and review on MTT studies including 'metric' or 'interval scale' was performed in the health and social sciences literature. The search was restricted to 2001-2005 and 2011-201...
