.getNumSample( desiredFC, power, alpha, delta, median_sigma_error, median_sigma_subject )
| desiredFC | the range of a desired fold change which includes the lower and upper values of the desired fold change. |
|---|---|
| power | a pre-specified statistical power which defined as the probability of detecting a true fold change. TRUE represent you require to calculate the power for this category, else you should input the average of power you expect. Default is 0.9 |
| alpha | significance level |
| delta | difference between means (?) |
| median_sigma_error | median of error standard deviation |
| median_sigma_subject | median standard deviation per subject |
