Next, we used a Monte Carlo simulation to establish the rank of the observed statistic in relation to the simulated values.
This procedure was repeated 10,000 times to construct the null distribution, and the position of the test's statistic in relation to this distribution was determined.
Given that age is strongly associated with all late-life outcomes, the change in the Wald statistic in relation to age after introduction of the various index variables is another way to understand their impact.
AC1 w, Gwet's first order agreement coefficient (quadratic weights); NA, not applicable Data in boldface indicate the most appropriate statistic in relation to the respective MEONF-II outcomes.
The most important statistic in relation to the underlying cause of the severe impairment of XY Sry- fertility and the improved fertility of XYd-1 is the proportion of embryos that reach the blastocyst stage by 5.5 dpc: 1.7% for XY Sry- but 43.2% for XYd-1.
Recursive descent partition analysis was used to identify the strongest divisor of all factors, and the most significant split determined by the largest likelihood-ratio chi-square statistic in relation to clinical response as described previously (Hoffmann et al, 2008, 2009).
CMT: Central macular thickness, HbA1c: glycosylated hemoglobin, p; statistic value, r: relation between two variables.
While each adjustment approach found differing results, it is also important to consider assumptions of the scan statistic models in relation to the data being used.
PCC was chosen as a representative of the global similarity measures used in traditional clustering algorithms, while we included the χ-statistic because of its relation to the combinatorial statistic used by ENIGMA (see Algorithm section).
Nonetheless, anticipating the use of its estimate τ ^ a 2 as a summary statistic, we explore its relation to the concept of heritability (Lynch and Walsh 1998) in Appendix A. When outliers are suspected, maybe as a result of erratic measurement error, it can be desirable to model the phenotype as being sampled from a distribution with heavier tails than the normal distribution.
