I begin with reviewing some basic statistics on the computation of sample variance with a sample of N subjects. With a known or an unknown population mean, denoted by μ, the variance estimate is computed differently, given by σˆ2=∑i=1NYi−μ2N if μ is known∑i=1NYi...
The demand for large sample sizes has prompted researchers to “outsource” analyses to direct-to-consumer companies, which employ discretion in their choice of tools, methods, and data—none of which are shared—and return the PCA loadings and other “summary statistics”27,28. Loadings are ...

We then estimated the intra-class correlations by taking appropriate ratios of identity probabilities, weighted Genetic detection of sex-biased dispersal JD Cooper et al according to the number of pairs in each sample (see Rousset, 2007), following the definitions of F-statistics as functions of ...
Even when a variant discovered in a single sample is truly associated with an exposure, the effect sizes of variants identified within a single sample are, by the nature of their discovery, likely to be larger than in the overall population (the Beavis effect, or Winner's Curse) (Goring et...
Statistics was performed with one-way ANOVA Holm-Sidak's multiple comparisons test using Graphpad Prism 6. pathway. Of note, HU910 and HU308 were well-balanced ligands without significant bias towards any signal transduction pathway on hCB2R. Of note, HU910, HU308 and JWH133 were ...
The difference in the strength of the correlation is not owing to sample size, as none of 10,000 randomizations where 310 non-homogenous genes were randomly sam- pled gave a correlation between GC3 and body mass that was equal to or weaker (that is, less negative) than that observed for...
