BACKGROUND Laboratory studies often involve analyses of highly skewed data for which means are not an adequate measure of central tendency because they are sensitive to outliers. Attempts to transform skewed data to symmetry are not always successful, and medians are better measures of central tendency for such skewed distributions. When medians are compared across groups, confounding can be an...

Background and aims: Internet seems to be increasingly involved a major part of the daily lives of population. In recent years, many reports have confirmed the huge number of internet users worldwide. This article is seeking to explore the factors contributing to the tendency to internet in students of Shahrekord University of Medical Sciences (SKUMS) and aimed to recommend some preventive stra...

This approach is the standard one when one uses parametric compartmental pharmacokinetic (PK) models. The usual parameter values are either the mean or median as the descriptor of the central tendency, and the standard deviation (SD) as the measure of dispersion. The usual distribution is the common Gaussian bell-shaped curve. Usually the mean is the central value used, and the distribution is ...

The relationship of forecast combination to recent developments in the theory and practice of model selection (in particular, the encompassing literature) is explored, the pragmatic virtues of forecast combination are argued, and a synthesis is attempted. Promising areas for future research, particularly exploration and development of forecast combination methodologies that facilitate ‘shrinkag...
