Objectives: The objective of this study is to provide examples situations in which the relative ranking age-standardized rates depends on choice standard population and emphasize importance selecting an appropriate population.Methods: Mathematical methods are used for elaborate variance rates. Examples from international comparisons suicide regional cancer incidence Korea were used.Results: wor...

background and aims: trends in deaths and medical admissions in the uk and europe show evidence for a series of infectious-like events. these events have been overlooked by traditional surveillance methodologies. preliminary evidence points to a rise in medical admissions in australia around the same time as those observed in europe, and this study was aimed to evaluate whether the deaths are o...

This article discusses the risks of standardization and ipsatization in longitudinal studies. First, it summarizes some common purposes of standardization in psychological studies. Second, it explains why and when standardization and ipsatization are problematic in the analysis of longitudinal data and profiles. Third, it shows alternative ways to achieve similar purposes while avoiding the risks.

The application of mixture models to flexibly estimate linear and nonlinear effects in the SEM framework has received increasing attention (e.g., Jedidi et al., 1997b; Bauer, 2005; Muthén and Asparouhov, 2009; Wall et al., 2012; Kelava and Brandt, 2014; Muthén and Asparouhov, 2014). The advantage of mixture models is that unobserved subgroups with class-specific relationships can be extracted (...

Most population-based mortality objectives and subobjectives in Healthy People 2000 are tracked using age-adjusted rates from the National Vital Statistics System (appendix table I). The exceptions are deaths from alcohol-related motor vehicle crashes, all motor vehicle crashes, and work-related injuries (objectives 4.1, 9.3, and 10.1), which are monitored with crude death rates from other data...

Additive manufacturing (AM) has the potential to create geometrically complex parts that require a high degree of customization, using less material and producing less waste. Recent studies have shown that AM can be an economically viable option for use by the industry, yet there are some inherent challenges associated with AM for wider acceptance. The lack of standards in AM impedes its use fo...

Clinical photography in the field of oculoplastic surgery has many applications. It is possible for clinicians to obtain standardized clinical photographs without a studio. A clinician photographer has the advantage of knowing exactly what to photograph as well as having immediate access to the images. In order to maintain standardization in the photographs, the photographic settings should rem...

The Computational Modeling in Biology Network (COMBINE) is a consortium of groups involved in the development of open community standards and formats used in computational modeling in biology. COMBINE's aim is to act as a coordinator, facilitator, and resource for different standardization efforts whose domains of use cover related areas of the computational biology space. In this perspective a...
