Ratios and effect size. [PDF]

open access: yesJournal 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.

The hierarchical island model revisited

open access: yesGenetics 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 =
