Exploring the Distribution for the Estimator of Rosenthal's 'Fail-Safe' Number of Unpublished Studies in Meta-analysis
Konstantinos C. Fragkos, Michail Tsagris, Christos C. Frangos
The present paper discusses the statistical distribution for the estimator of Rosenthal's 'Fail-Safe' number NR, which is an estimator of unpublished studies in meta-analysis. We c…
A novel, divergence based, regression for compositional data
Michail Tsagris
In compositional data, an observation is a vector with non-negative components which sum to a constant, typically 1. Data of this type arise in many areas, such as geology, archaeo…
Publication Bias in Meta-Analysis: Confidence Intervals for Rosenthal's Fail-Safe Number
Konstantinos C. Fragkos, Michail Tsagris, Christos C. Frangos
The purpose of the present paper is to assess the efficacy of confidence intervals for Rosenthal's fail-safe number. Although Rosenthal's estimator is highly used by researchers, i…
Regression analysis with compositional data containing zero values
Michail Tsagris
Regression analysis with compositional data containing zero values
The k-NN algorithm for compositional data: a revised approach with and without zero values present
Michail Tsagris
In compositional data, an observation is a vector with non-negative components which sum to a constant, typically 1. Data of this type arise in many areas, such as geology, archaeo…
Improved classification for compositional data using the -transformation
Michail Tsagris, Simon Preston, Andrew T. A. Wood
In compositional data analysis an observation is a vector containing non-negative values, only the relative sizes of which are considered to be of interest. Without loss of general…
