Bootstrap resampling for 10,000 replications and a relative sample size of 1 was used to generate the bootstrap probability values, as implemented in the pvclust package v.1.2-1 [ 38].
Assuming a prevalence of premarital sexual behaviors of 4.8% [ 14] among senior high school students, an α of 0.05, and a relative sampling error of 0.1P, we calculated a required sample size of approximately 13,000 to allow for the larger sampling error of the complex samples procedure and an non-response rate of 10%.
By contrast, the only one study using ReHo in SAD before found significantly decreased ReHo mainly in the DMN and central executive network (CEN) while it found increased ReHo in occipital regions and the right putamen in a relative small sample of SAD patients via mass-univariate analysis [ 27].
A plot of relative sample size versus number of replicate arrays is also automatically generated.
For the majority of curves, the RMSE fell below 0.01, within a relative small sample size of 200 used for curve fitting.
First, this study has a relative small sample size of 26 health centers, and possible low statistical power, given a wide variability among health centers in providing HIV/AIDS services and the number of covariates in the regression models.
First, although the study achieved a relative large sample size, the age span of the sample range too large, which may be possible selection bias exists.
In some time-known scenarios, negative selection was simulated by adjusting the relative sampling probability of a TE insertion during the Wright Fisher process.
The decision to study the riding activity in such a systematic and detailed manner and the complexity of the data collection procedure meant the recruitment of a relative reduced sample.
For endometrial biopsy specimens from across the menstrual cycle, results are given as quantity relative to a comparator, a sample of RNA from the liver.
