Standard deviation and standard error of the mean [PDF]
Korean Journal of Anesthesiology, 2015 In most clinical and experimental studies, the standard deviation (SD) and the estimated standard error of the mean (SEM) are used to present the characteristics of sample data and to explain statistical analysis results.

Beta-Cauchy Distribution: Some Properties and Applications [PDF]
Journal of Statistical Theory and Applications (JSTA), 2013 Some properties of the four-parameter beta-Cauchy distribution such as the mean deviation and Shannon’s entropy are obtained. The method of maximum likelihood is proposed to estimate the parameters of the distribution.

The value of reliability [PDF]
, 2007 We derive the value of reliability in the scheduling of an activity of random duration, such as travel under congested conditions. We show that the minimal expected cost is linear in the mean and standard deviation of duration, regardless of the form of ...
