Our specific aims were to evaluate the power of bivariate analysis and to compare its performance with traditional univariate analysis in samples of unrelated subjects under varying sampling selection designs. Bivariate association analysis was based on the seemingly unrelated regression (SUR) model that allows different genetic models for sample size, and population effect size. 5. Sensitivity analysis (see Cohen, 1988; Erdfelder, Faul, & Buchner, 2005). The required population effect size is computed as a function of significance level α, sta-tistical power 12β, and sample size. As already detailed and illustrated by Faul et al. (2007),

You analyze the data using tools such as t-tests and chi-squared tests, to see if the two groups of data correlate with each other.
30-11-2010 · The analysis of a baseline predictor with a longitudinally measured outcome is well established and sample size calculations are reasonably well understood. Analysis of bivariate longitudinally measured outcomes is gaining in popularity and methods to address design issues are required. The focus in 8-4-2019 · One issue with using tests of significance is that black and white cut-off points such as 5 percent or 1 percent may be difficult to justify. Significance tests on their own do not provide much light about the nature or magnitude of any effect to which they apply. One way of shedding more light on

Analysis of bivariate longitudinally measured outcomes is gaining in popularity and methods to address design issues are required. The focus in 30-11-2018 · The selected copula functions and the corresponding conditional and joint return periods are calculated and the results are compared with the marginal univariate estimations of each variable. Results highlight the effect of sample size on univariate and bivariate rainfall frequency analysis for hydraulic engineering design practices.
