| Because of concern for sampling error, documentation of regression requires an ample biopsy followed by examination of the entire liver. |
| This sampling error causes random fluctuations in allele frequencies called genetic drift. |
| This is because the statistical sampling error of the phase is inversely related to the squared coherence. |
| In addition to these caveats, sampling error due to analysis of an inadequate sample volume can also lead to a false-negative test result. |
| Usually, however, the systematic component of sampling error is very small in relation to its random component. |
| These estimates are not published because they may present too great a sampling error. |
