On the Use of the Jackknife to Compare R<sub>XY</sub> Statistics in Conservation Genomics Research. [PDF]

open access: yesMol Ecol Resour
ABSTRACT Many useful quantities in conservation genomics are point estimates that summarise genetic variation at the population or species level. This presents a challenge to the application of null hypothesis testing frameworks, which require some measure of uncertainty to test the authenticity of measured group differences.

Jackknife, Bootstrap and Other Resampling Methods in Regression Analysis

open access: yesThe Annals of Statistics, 1986
Statistical inference based on data resampling has been mostly based on the assumption of independence and identical distribution, the i.i.d. case. The author maintains that resampling methods justifiable in the i.i.d. case may not work in more complex situations. These methods are studied in the context of regression models.

The proper application of logistic regression model in complex survey data: a systematic review [PDF]

open access: yesBMC Medical Research Methodology
Background Logistic regression is a useful statistical technique commonly used in many fields like healthcare, marketing, or finance to generate insights from binary outcomes (e.g., sick vs. not sick).

Genomic Variation and Population Structure of Portuguese Native Dog Breeds. [PDF]

open access: yesAnim Genet
ABSTRACT The presence of dogs in Portugal is confirmed by zooarchaeological evidence dating to at least 7600 years ago. The 11 native dog breeds that exist in this territory are therefore the end‐product of a complex evolutionary process. This study characterises the genomic diversity and population structure of 10 native breeds based on whole‐genome ...

The efficiency of different search strategies in estimating parsimony jackknife, bootstrap, and Bremer support

open access: yesBMC Evolutionary Biology, 2005
Background For parsimony analyses, the most common way to estimate confidence is by resampling plans (nonparametric bootstrap, jackknife), and Bremer support (Decay indices).

Species Distribution Models and Abundance Estimates Enhance Breeding Bird Atlas Data [PDF]

open access: yesEcol Evol
Our primary goal was to leverage the large amount of systematic and volunteer‐based data produced by the Minnesota Breeding Bird Atlas to develop species distribution models and population estimates for as many breeding bird species as possible. We utilized three complementary techniques to develop species distribution models and maps for 136 breeding ...

Complementary Evidence From Historical and Contemporary Gene Dispersal Reveals Contrasting Population Dynamics in a Tropical Tree Species. [PDF]

open access: yesEvol Appl
ABSTRACT Gene flow shapes the demographic stability and evolutionary potential of tropical forest trees, yet its dynamics may differ depending on the temporal scale at which it is assessed. We combined spatial genetic structure (SGS), parentage analyses, and reproductive success metrics to investigate historical and contemporary gene dispersal in four ...
