Parameterrhois a correlation coefficient that measures the dependence between the outcome and participation models. Ifrhois zero, the two models are independent and can be analyzed separately. In other words, there is no sample selection, and we can model the wages using only the sample of women...

(Supplementary Fig.10a; Supplementary Data4a and4b). A 2-way hierarchical clustering was performed for all ChIP-seq data by pairwisely calculating the Spearman’s correlation coefficient (Supplementary Fig.10b). The principle component analysis (PCA) demonstrated that AL-treated and TRF-treated ...
Mann–Whitney–Wilcoxon test MWW test stats (wilcox.test) The MWW test is a nonparametric test of the null hypothesis. And it is well suitable when the assumptions of the t test or the data is ordered are not met. J Wound Ostomy Continence Nurs. 24:12, 1997 Correlation-based feature sel...
·2 episodes per 1000 population, losses to follow-up of 10%, and no design effect from cluster randomisation. The last assumption was made because lead-in surveillance for cholera in the study site showed no clustering of cholera within residential dwellings (intracluster correlation coefficient ...

Pearson's correlation coefficients were generated using the cor function from the stats package (v4.2.2) to measure correlation between a) the two individual-level outcome variables (GHQ-12 and SF12-MCS) and b) the effect sizes (betas) across outcomes in the main analyses. Welch's two sam...
Meta-analysis is usually applied to parametric effect sizes, particularly the standardized mean difference or the point bi-serial correlation coefficient, but Cliff's d and pˆ both conform with the three criteria reported above. In addition, Kromrey et al. (2005) proposed applying meta-analysis...
