Confidence Intervals from Normalized Data: A correction to Cousineau (2005) [PDF]

open access: yesTutorials in Quantitative Methods for Psychology, 2008
Presenting confidence intervals around means is a common method of expressing uncertainty in data. Loftus and Masson (1994) describe confidence intervals for means in within-subjects designs. These confidence intervals are based on the ANOVA mean squared

Genome sequence-based species delimitation with confidence intervals and improved distance functions

open access: yesBMC Bioinformatics, 2013
For the last 25 years species delimitation in prokaryotes (Archaea and Bacteria) was to a large extent based on DNA-DNA hybridization (DDH), a tedious lab procedure designed in the early 1970s that served its purpose astonishingly well in the absence of ...
