A forward-stepping approach was used to develop a final model, with P ≤ 0.05 set as the criterion for inclusion of the independent variables into the final model based on a conditional t-test (Pinheiro and Bates, 2000).
This was done using a conditional hypergeometric test; conditioning means that each term was tested for statistical overrepresentation after removing genes that overlapped a significant child term.
Statistical significance was tested using a Student's t-test.
Disease-specific costs (dengue vs. non-dengue) were compared using a paired t-test or a conditional logistic regression model and the Wald χ-test.
These data were analyzed using a two-tailed t-test.
Statistical significance was calculated using a two-tailed t-test.
Statistical analysis was done using a two-tailed T-test.
Data were analyzed using a two-sided t-test.
We measure the degree of transitivity in the transnational terrorism network over time using a conditional uniform graph (CUG) test.
Continuous measures were tested using an independent sample t-test.
