I have some problem in my statistics, I have two sample size one 18 and other 17 when i test normality, from Shapiro test(R) presenting p values of 17(sample size) 0.007442i.e p is less than o.o5 and (18 sample size) 0.3423 i.e p is greater than o.o5 respectively. With the...
like to do (e.g., what confidence intervals you are using). Power analysis is a technique for mathematically evaluating the smallest sample size needed based on your needs. Another rule of thumb is that your sample should be large enough, but no more than 10% as large as the population....
Using simulation methodology four parameters were manipulated for the two group design: (1) ratio of population variances; (2) distribution form; (3) sample size and (4) population mean difference. The results indicated that while the rank transform approach was less......
Although we can put any per cent of the potential loss and inflate the sample size, it doesn’t guarantee that the calculated sample size is valid in terms of representative sample. In general, we would recommend that less than 10% loss would be an acceptable loss. However, there are diff...
When the expected ratio of the AUCs was less than or equal to 1, the power of the Fieller-type confidence interval was larger than the asymptotic confidence interval. If the expected ratio of the AUCs was larger than 1, the asymptotic confidence interval had greater power. Sample size can ...
than responding to the (mostly inappropriate) concerns of a more dominantpositivist paradigmand their numerical expectations. Sample sizes in qualitative research are guided by data adequacy, so an effective sample size is less about numbers (n's) and more about the ability of data to provide a...
The results elicited that the good effect sizes (more than 0.8) exhibited higher performance (> 90%), while poor effect sizes (less than 0.2) showed poor ML performance (< 80%). Previous studies reported that a good effect size demonstrates a higher difference between two groups, ...
On-disk size in MB 2312 As you can see, there is a big discrepancy between the on-disk size of the checkpoint files, which is 2.3 GB, and the actual data size, which is closer to 30 MB. Looking closer at where the disk-space utilization comes from, you can use the following query...
Runtime is dependent on the size of the input file. Based on our benchmarking experiments, runtimes are <10 min for DNAse-seq, <30 s for ChIP-seq, and are on average about 2 h for RNA-seq datasets. For VCF mode, Crosscheck requires approximately 2.5 gb of ram for a ...
