A Robust Effect Size Index [PDF]
Psychometrika, 2020 Effect size indices are useful tools in study design and reporting because they are unitless measures of association strength that do not depend on sample size. Existing effect size indices are developed for particular parametric models or population parameters. Here, we propose a robust effect size index based on M-estimators.

Journal of Experimental Psychology: Animal Learning and Cognition, 2017 Responding to a related pair of measurements is often expressed as a single discrimination ratio. Authors have used various discrimination ratios; yet, little information exists to guide their choice. A second use of ratios is to correct for the influence of a nuisance variable on the measurement of interest.

Effective population size [PDF]
Current Biology, 2002 What is it? An aid to calculation in population genetics, introduced by Sewall Wright. The rate of change of the genetic make-up of a population by genetic drift – fluctuations in allele frequencies caused by random sampling – is inversely related to the effective population size, Ne. Ne is measured with reference to an ideal ‘Wright–Fisher’ population.

The hierarchical island model revisited
Genetics Selection Evolution, 2000 Formulae were derived for the genetic differentiation between populations within a metapopulation (FSM), and between metapopulations (FMT) as functions of migration and mutation rates, size and number of populations and metapopulations. We show that FMT =

Tumor size and effectiveness of electrochemotherapy [PDF]
Radiology and Oncology, 2013 Electrochemotherapy (ECT) is an effective and safe method for local treatment of tumors. However, relatively large variability in effectiveness of ECT has been observed, which likely results from different treatment conditions and tumor characteristics.
