However, when the whole variance matrix was used in the calculations (instead of using only regression parameters to calculate the WLS statistic), the sizes of WLS 0.95 confidence sets did not change (not shown).
Sample size was determined using a more conservative effect size (effect size statistic [d=] 0.25) than that used in a previous study [ 27].
The evaluative [longitudinal] validity, i.e., responsiveness, of the MacNew has been tested with three different effect size statistics, the effect size statistic [ES], the standardized response mean [SRM], and the responsiveness statistic [RS].
To evaluate if there is any significant statistical difference between the different types of concurrency bugs, we use a Wilcoxon Signed Rank test and calculate the A-statistic effect size.
The need for using many more importance samples when applying DF.IS to the HS rather than to the pre-CC is illustrated in Figure 8, which shows for DF.IS analysis of 10% QTL the distribution of the effective sample size (ESS) statistic (see Statistical Models and Methods).
This is done by creating simulated snowball samples from the simulated networks and then minimizing their distances from an observed network statistic across network sizes.
Cohen's d statistic for effect sizes was computed for individual contrasts [39].
By re-shuffling the data sets to produce the null distribution of a cluster size statistic, the test makes few assumptions as to the statistical properties of the SPM, and thus it is valid under a broad range of conditions.
Comparisons that were statistically significant were further tested with an effect size statistic, using pooled standard deviation (Morgan et al, 2007) to assess the magnitude of the difference.
The sample weight was applied in the bivariate analyses to adjust for inflation of the chi-square statistic by the size of the estimate by weighting the estimate back down to the original sample size.
