Detecting differentially expressed genes in heterogeneous diseases using control-only analysis of variance

open access: yes, 2014
Purpose: Microarray technology allows for simultaneously screening many genes and determining which gene(s) are differentially expressed in different disease statuses or different cell types.

Objective evaluation of precision requirements for geochemical analysis using robust analysis of variance [PDF]

open access: yes, 1992
The pursuit of high precision in geochemical analysis has no inherent limit. An appropriate analytical precision requirement can be set, however, by comparing the “analytical variance” with the other sources of variance in geochemical data.The purpose of

An Efficient SDN load balancing scheme based on variance analysis for massive mobile users [PDF]

open access: yes, 2015
In a traditional network, server load balancing is used to satisfy the demand for high data volumes. The technique requires large capital investment while offering poor scalability and flexibility, which difficultly supports highly dynamic workload ...

ACCURACY ASSESSMENT OF HEIGHTS OBTAINED FROM TOTAL STATION AND LEVEL INSTRUMENT USING TOTAL LEAST SQUARES AND ORDINARY LEAST SQUARES METHODS

open access: yesGeoplanning: Journal of Geomatics and Planning, 2016
Spirit levelling has been the traditional means of determining Reduced Levels (RL’s) of points by most surveyors.  The assertion that the level instrument is the best instrument for determining elevations of points needs to be reviewed; this is because ...

Statistical results on restorative dentistry experiments: effect of the interaction between main variables

open access: yesJournal of Applied Oral Science, 2010
Statistical analysis interpretation is a critical field in scientifc research. When there is more than one main variable being studied in a research, the effect of the interaction between those variables is fundamental on experiments discussion. However,

One-way analysis of variance with unequal variances. [PDF]

open access: yesProceedings of the National Academy of Sciences, 1989
We have designed a statistical test that eliminates the assumption of equal group variances from one-way analysis of variance. This test is preferable to the standard technique of trial-and-error transformation and can be shown to be an extension of the Behrens-Fisher T test to the case of three or more means.

Solid Pseudopapillary Neoplasm of the Pancreas in Children and Adolescents: Expert Recommendations

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Solid pseudopapillary neoplasm of the pancreas (SPN) is a rare low‐grade malignant exocrine pancreatic tumor, mostly discovered during the second decade of life in females, with a very good prognosis, provided microscopically complete surgical excision is achieved.
