Nominal analysis of “variance” [PDF]

open access: yesBehavior Research Methods, 2009
Nominal responses are the natural way for people to report actions or opinions. Because nominal responses do not generate numerical data, they have been underutilized in behavioral research. On those occasions in which nominal responses are elicited, the responses are customarily aggregated over people or trials so that large-sample statistics can be ...

Analysis of variance components reveals the contribution of sample processing to transcript variation [PDF]

open access: yes, 2009
The proper design of DNA microarray experiments requires knowledge of biological and technical variation of the studied biological model. For the filamentous fungus Aspergillus niger, a fast, quantitative real-time PCR (qPCR)-based hierarchical ...

Mean-risk models using two risk measures: A multi-objective approach [PDF]

open access: yes, 2006
This paper proposes a model for portfolio optimisation, in which distributions are characterised and compared on the basis of three statistics: the expected value, the variance and the CVaR at a specified confidence level.

Anthropometric and physical characteristics allow differentiation of young female volleyball players according to playing position and level of expertise

open access: yesBiology of Sport, 2016
The aim of our study was to determine the differences in some anthropometric and physical performance variables of young Croatian female volleyball players (aged 13 to 15) in relation to playing position (i.e., independent variable) and performance level

Aspects of average response computation by aperiodic stimulation [PDF]

open access: yes, 1972
A mathematical analysis of the variance of the average evoked-response computation as a function of the numberN of stimuli presented is made for the case when the response is disturbed by additive stationary noise.

DISCO analysis: A nonparametric extension of analysis of variance

open access: yes, 2010
In classical analysis of variance, dispersion is measured by considering squared distances of sample elements from the sample mean. We consider a measure of dispersion for univariate or multivariate response based on all pairwise distances between-sample
